Sadly, TMI is only awarded a creep factor of 1 as Clary and Jace are not related in truth. Game of Thrones gets a 9! 

Spoilers for CoHF and Clockwork Princess!

usamahayat said: Hi, first of all I love your books! I have a question though, when jem becomes mortal again his years don’t catch up to him but if magnus were to become mortal his years would catch up to him and he would die. Why did this not happen to jem?

missmorgenstern said: Hi Cassie!:) I just want to say that I love your books, and those who critique them need plonking on the head! My question though is about Jem and Magnus: In CoHF when Magnus’s father was going to take Magnus’s immortality, Magnus said that he would most definitely die because the years would come at him all at once. So why did Jem not die when he became mortal again after being a Silent Brother?

Hey Cassie! I’ve just finished reading Heavenly Fire and I can now safely say that I love your books and can not wait for you to release the rest! However, I do have a question about Jem becoming mortal again. In TMI, when they were in Edom, Magnus's father wanted his immortality but Magnus said that if he gave it up, he would die as his age (of over 400 years old) would catch up on him immediately. How come this didn’t happen with Jem, after he became mortal again as he is over 130 years old?”

When I get a ton of questions that are all the same question all at once I tend to assume some sort of Conversation is happening somewhere on the internet and everyone is stumped so they are like LET’S ASK CASSIE. Which is fine. I don’t mind.

This falls into the category of questions I think of as “Why are spaghetti and fettucine both pasta when they’re different shapes?” We know the answer because we know pasta is not all one thing. Magic, also, is not all one thing, and neither are magical creatures. Different magic acts on people differently. (Being injected with demon blood worked on Sebastian differently than having a demon parent worked on Tessa. Having a demon parent and a Shadowhunter parent produces a different creature (Tessa) than having a demon parent and human parent produces (Magnus.)) If Maia drank Jace’s blood (no idea why she’d want to) she would not become a Daylighter, because she is not a vampire. Sometimes we want to think of magic as “Do A, Get B” but the magic system of the Shadowhunter books is complicated: if you Do A, it depends on why you are doing it, and with what, and to whom. So:

1) Jem and Magnus are not the same magical creature. Magnus is a warlock. Jem is a Silent Brother.

2) Magnus and Jem are not both immortal. Magnus is immortal. Silent Brothers are not. They simply age very slowly. When Jem shows up on the bridge in Clockwork Princess, he looks as if he’s aged about four, five years since 1878.

3) Magnus was going to have his immortality taken away. Jem did not have his (nonexistent) immortality taken away: he had his Silent Brotherness taken away. The aging slowly is a an aspect of being a Silent Brother, but not the point of the exercise or a significant part of the magic.

4) Magnus was going to have the spell performed on him by a demon. Jem had his true self restored by literally the fire of heaven. It is a central tenet of the Shadowhunter books that from angelic power comes good things, and from demonic power comes bad things. That is why Heaven probably does not look like Edom. 

What would have happened to Magnus was a deliberate evil spell performed by a demon, who desired to consume Magnus’ immortality for his own. What happened to Jem was a restoration, a burning away of the poison that made Silent Brotherhood necessary and then of Silent Brotherhood itself. 

In other words they were completely different kinds of magic, performed by completely different forces on completely different beings under completely different circumstances. When Magnus says that if Asmodeus takes his immortality away in Edom, he’ll die, he knows he’ll die under those circumstances. Obviously he doesn’t think he would die under any and all circumstances, or that this is a hard and fast rule that applies to all immortals all the time, or why would he ever have bothered to look in the Book of the White and elsewhere for a way to undo his immortality in the first place? 

Hopin’ that helps!

Hi Cassandra!!! I have fallen absolutely in love with your books. I find it utterly amazing how you created a completely new race and how the shadow hunters history is so entwined with old stories. Anyway, my question is: why caves? Do the herondales just have a thing for caves? Did you know decide about the others cave experience while righting one of the experiences? Because really caves are kid of kinky. Thank you for your time!!!


I don’t think the Herondales have a thing for caves, given that both times a Herondale has gotten busy underground, it’s not been their choice. They’re not like:


I actually never even mentally connected up Jace and Clary’s underground lake and Tessa and Will’s prison under the mountain as being remotely similar until readers started asking about it. Which goes to show that a lot of what seeps into our consciousness, as writers, is in fact … unconscious.

I mean, maybe I like caves, given that the entirety of Magisterium is set in a cave, so if anyone ever gets busy, it will again be IN A CAVE. And there was a sea cave in Lady Midnight where some action happened but I took it out because of all the questions about caves. I decided I didn’t want to be remembered as a cave pervert.

Reblogged to add:

drink-up-this-wonderful-life said: Wait….did you take the scene completely out of Lady Midnight or did you just move it to somewhere besides a cave? Because I don’t think you’re a cave pervert which means I shouldn’t miss out on the action that was going to happen in said cave….right?? Right?!

The action happens exactly the same, just not in a cave.

I may not be the only pervert. :)

Hi Cassie After reading all the TMI, TID and TMBC books I still don’t get why Will Herondale is such a touchy subject for Magnus. I mean, yes, they were friends and we know Magnus told Camille they were dating even tho they weren’t and Magnus had helped Will and Tessa many times but there was nothing that explains (unless I totally missed it) why talking about Will made Magnus sad. Why did he kept referring to Will as a painful memory and why on earth did Alec even think they had feelings for each other. Was Magnus inlove with Will and was upset that it was one sided? Did Will somehow hurt Magnus along the years? I’m still confused about the whole thing. I’d be super grateful if you could shed some light on the matter. Thank you so much for your books! — nicky-angel  

“Are you in love with Will?” Woolsey asked—all curiosity, no jealousy.

“No,” Magnus said. “I have wondered that, but no. It is something else. I feel that I owe him. I have heard it said that when you save a life, you are responsible for that life. I feel I am responsible for that boy. If he never finds happiness, I will feel I have failed him. If he cannot have that girl he loves, I will feel I have failed him. If I cannot keep his parabatai by him, I will feel I failed him.” —Clockwork Princess

Will did find happiness, and Will did get the girl he loved. Will did not get to keep his parabatai by him. So Magnus feeling he failed Will in that would be the simplest explanation for Magnus’ feelings of sadness regarding Will, and the one that Magnus plainly says is the reason.

Text is open to interpretation, of course, and you don’t always have to agree with the characters. My perspective is that Magnus’s sadness/wistfulness/sentimentality about Will springs from a few different sources:

1. The one Magnus stated, above. He feels he failed Will.
2) Thinking of Will reminds him of his own immortality. Remembering people he cared about and lost sometimes makes him sad. He cared about Will, and Will is dead. What’s not to be sad about?

3) Magnus had a front row seat to Tessa’s heartbreak when Will died. As another immortal, her great love for a mortal was symbolic for Magnus. We think of Tessa as someone with a lot of equanimity and wisdom, but at the time she was probably miserable. Magnus was likely one of her main supports at that time, and thus he probably saw the worst of it. And  wouldn’t that remind him of him and Alec?

3. When Magnus thinks of Will, he doesn’t just think of Will as he was the last time Magnus saw him in CP, as Will-with-a-happy-ending. He thinks of all the Wills he knew over time, including the tortured young man, and the Will that grew old, and the absence of Will that broke Tessa’s heart.
Lastly, Alec thought Magnus was in love with Will because he was repeatedly manipulated by Camille into fixating on the idea that he was. But the reason Alec was so vulnerable to that manipulation was that Magnus refused to communicate about his past. (More about that here:
Simon and his memory.


bethaniebooks said: EEEEEEEEEK!!! Hi! Um, I’m like so nervous right now!! I am a HUGE fan of TMI and so is my best friend, we talk about it almost every day…but I have to ask…WHY DID YOU MAKE SIMON LOSE HIS MEMORY?! Me and my friend cried for like a week straight! I just have to know…*sigh*

Simon losing his memory was set up in City of Lost Souls, when Azazel takes a memory from each of Team Good, indicating that demons trade in memories.

Simon lost his memory because though I planned a hopeful and sweet more than bitter ending for TMI, I didn’t think it was an ending that should come entirely without consequence. Consequences are part of the theme of the books, thus the quote from Ted Hughes that opens City of Fallen Angels:

Nothing is free. Everything has to be paid for.
For every profit in one thing, payment in some other thing. For every life, a death. Even your music, of which we have heard so much, that had to be paid for. Your wife was the payment for your music. Hell is now satisfied. 

There was no way for Team Good to get out of Edom without paying a huge price. Sebastian’s life isn’t a huge price, because they came there to kill him, so accomplishing what you came there to do, however that might prick you with regrets, isn’t a huge price. They lost Raphael, but that was before the majority of Team Good even got there, and Raphael didn’t come to Edom willingly — he was forced. Being kidnapped and then killed isn’t a consequence for a choice you made.

It was important to me that Team Good be brave and willing to sustain losses to save the world. They chose to go to Edom, knowing they’d probably never come back. They were gifted with a way to come back, but that way had to come at a terrible price. It could have been any of them that volunteered to die — they all did volunteer to die. It could have been Magnus’ life, but since they pretty much forced Magnus to call upon his father in the first place, that’s very uncomfortable. When Team Good forces one of their members to do something they didn’t want to do and the result is that that member dies, Team Good may have to become Team Morally Compromised.

Not to mention I’m not sure it’s something Alec would have survived.

For every profit in one thing, payment in some other thing. They all got out of Edom, even Simon. The payment was Simon’s memories. They could all otherwise have gotten out of Edom with no payment at all, but then they look pretty stupid for having been so worried about going to Edom in the first place as it is clearly a cakewalk where you get to have sex in caves. Everyone should go to the demon realms! They have skiing! 

As for why memories?! why Simon?! — well, removing any else’s memories would have meant throwing them out on the streets of a world where they had no way to survive; they’re all Shadowhunters or magical creatures. Simon had a life to go back to. It was a survivable if agonizing compromise. It is also a choice that hits pretty much all of them where it hurts. They’re Shadowhunters. Simon’s not. They should have protected him. They couldn’t. Save the world and lose a piece of your heart; that’s a consequence.

Hi Cassie :) About Simon - I was wondering what exactly your reasoning was behind having Simon become a shadowhunter. In one of your old blog posts (I can’t remember which), you said you thought he “deserved” to become a shadowhunter after fighting alongside them for so long. But I feel like that implies vampires aren’t as good as shadowunters, something Simon and Alec talked about. From what I understood, it wasn’t okay for Alec to think Simon was beneath him simply because he was a vampire, but doesn’t what you stated imply that vampires aren’t on equal standing with shadowhunters? Also, now that Simon is mortal again, on the path to becoming a shadowhunter and also capable of having children, doesn’t that make all of his struggles throughout the series meaningless? I enjoyed watching Simon struggle with his identity and accepting his vampirism (if that’s a word), and I really liked the whole Mark of Cain thing. But if all of that is reversed, what was the point of his struggles? I just feel like his ending was too perfect. But I’m sure you have some reasoning behind it all, and I’d be honored if you’d share it with us. Thanks so much!!

I put these two questions side by side to illustrate the variety of reader response. From the idea that what happened to Simon is unbearable to the idea that what happens to Simon is too perfect, everyone has their different take. And as I believe all personal takes are valid, all I can do is give you my take. It may mean I disagree or we focus on different things but it doesn’t mean I think your reading is invalid. Just wanted to get that our of the way.

. In one of your old blog posts (I can’t remember which), you said you thought he “deserved” to become a shadowhunter after fighting alongside them for so long. But I feel like that implies vampires aren’t as good as shadowunters, something Simon and Alec talked about.

This is extra-book stuff as we’re now discussing my commentary on commentary. :) But I will say I don’t agree here. Simon deserved to become a Shadowhunter because it was something he wanted to be, not because it was something objectively better. Saying someone deserves something they want… not really the same as saying that what they don’t want is beneath them. If Simon had wanted to be a pilot and not a sailor, would that mean the text communicated ‘DAMN ALL SAILORS’?

I enjoyed watching Simon struggle with his identity and accepting his vampirism (if that’s a word), and I really liked the whole Mark of Cain thing. But if all of that is reversed, what was the point of his struggles? 

Simon lost the Mark of Cain in City of Lost Souls — traded it away for a weapon from Raziel. In fact, his speaking to Raziel was possibly the most Shadowhuntery thing anyone but Clary has done in TMI! Here is where we’re going to disagree textually (and that’s fine) — I never wrote Simon as accepting his vampirism, purposefully. He always hated it. He hated what happened with Maureen, he hated losing his family, he hated the idea of being in a clan, of living with other vampires. He didn’t have any vampire friends unless you count Raphael and that was always a tetchy relationship during which Raphael repeatedly told Simon that he was a terrible vampire because in fact he was. He was uniquely unsuited to it. The only thing he ever seemed to like about it was biting Isabelle and there are other things he could have done with Isabelle that he probably would have liked as much if not more.

(Lord Montgomery ponders.)

Also, now that Simon is mortal again, on the path to becoming a shadowhunter and also capable of having children, doesn’t that make all of his struggles throughout the series meaningless?

Jace is now free of the heavenly fire, knows who he is, knows the love of his life isn’t his sister, and is on a path to a happy life. Does that make all his struggles meaningless? Why would a happy ending specifically make anyone’s struggles meaningless? 

I mean, it could be that I am not understanding the question properly. From my point of view, Simon’s struggles — not wanting to be a vampire, not knowing how to deal with being rejected by his family, being always afraid vampires were going to spring at him for his yummy Daylighter blood — are simply being replaced with a different set of struggles. Simon is now an ex-Downworlder who is going to have to go train to become a Shadowhunter in a world where Shadowhunters, despite the progress made, still hate and distrust Downworlders, and everyone knows who he is. He has to go live in Idris, a place he doesn’t remember. He is also going to have to somehow come to terms with the fact that he no longer remembers a huge portion of his life. He doesn’t remember his childhood properly, or his best friend, or the girl he loves, or himself. He’s going to have to reconstruct an entirely new Simon out of the pieces he has and whatever he gets back. To me that is a much more interesting struggle.

Also, now that Simon is mortal again, on the path to becoming a shadowhunter and also capable of having children

All of these things are good things only if Simon wants them. Who wants to be mortal? I don’t, frankly. Others do. Not everyone would want to be  Shadowhunter. Simon luckily does, always has since book one. As for the children thing, who says he wants them or ever will? Not everyone wants children; not everyone has to have children to be happy. (Interesting post here about how difficult it is if you don’t want kids to find any kind of story that reflects your life and wants. “It seems in every other romance there must be a baby-epilogue, or baby-logue, with pregnancy and glowing and 2.5 children in the future. Which books feature heroines and heroes who are not interested in having children, whether it’s a major topic point or not? Which ones did you like best?”) TDA takes place when Simon would be 22, TWP when he would be 25. There’s no reason to think even if he wanted kids he’d have any in that time period or it would impact the story. (Besides, I think everyone assumed he’d wind up with Izzy as a vampire, and then they’d be together, and then they could perfectly well have kids by adopting them or with artificial insemination. Adopted children are your children. When Magnus and Alec adopt, that will be their kid. Sorry, tangential unrelated rant — my best friend has two biological kids, my other best friend’s son is adopted, and I don’t have kids. I get tired of hearing that only one of us has a family that is considered happy or acceptable.)


I don’t think that when struggles are over, they are rendered meaningless. I think that if there is something that feels weird about Simon’s ending, it is that everyone else gets what feels like closure. Simon gets what feels like an opening for more story. And there will be more story — in Tales from the Shadowhunter Academy, and even in TDA. I can see how that would make one feel “this ending is different/strange/why do I feel differently about it than the endings for the other characters?” And sometimes when things feel strange, we struggle to identify why – too happy, too sad, too overdetermined, too unclear? Maybe that explains the range of response to some extent. And also just that readers are always different people. A book is a bit of a kaleidescope – every person who looks in it will see the same glittering crystals, but never in quite exactly the same arrangement.

Jem’s hair and eyes: spoilery for CP2 and CoHF

writingonhands said: How do Jem’s eyes change back to a dark brown colour from silver? Was it something that happened while he was a silent brother? It’s a stupid question - I know but I have read and re-read TID, TMI, and After The Bridge -Your work is truly amazing- but I still don’t get it (maybe I missed a line or something) ? Thanks!

Thanks! Jem was not born with silver hair and eyes. They came from the side effects of the yin fen.

Clockwork Angel, page 341:
He flicked open the clasp on the box, and the lid slid back. Inside was a thick layer of what Tessa thought at first was ash, but the color was too bright. It was a layer of thick silvery powder almost the same bright silver color as Jem’s eyes.
“This is the drug,” he said. “It comes from a warlock dealer we know in Limehouse. I take some of it every day. It’s why I look so—so ghostly; it’s what drains the color from my eyes and hair, even my skin. I wonder sometimes if my parents would even recognize me. …”

As soon as Jem became a Silent Brother and ceased taking the drug, the silvery color began to fade from his hair and eyes. 

Clockwork Princess:

"“Jem?” she whispered. The sound of the vial being set down on the bedside table. A sigh. “Yes,” he said. “Tessa. Will you look at me?” She turned, and looked. And drew in her breath. It was Jem, and not Jem. He wore the parchment robes of a Silent Brother, open at the throat to show the collar of an ordinary shirt. His hood was thrown back, revealing his face. She could see the changes in him, where she had only barely seen them in the noise and confusion of the battle at Cadair Idris. His delicate cheekbones were scarred with the runes she had noticed before, one on each, long slashes of scars that did not look like ordinary Shadowhunter runes. His hair was no longer pure silver—streaks of it had darkened to black-brown, no doubt the color he had been born with. His eyelashes, too, had darkened to black. They looked like fine strands of silk against his pale skin—though he was no longer as pale as he had been.”

Tessa is seeing him during the transition, as the yin fen leaves him. When the heavenly fire returned him to being a human Shadowhunter, the yin fen had long drained from his system. Therefore his hair and eyes were dark.

Clockwork Princess pages 557-558: This was Jem. She couldn’t tear her gaze away from him. She had always thought Jem was beautiful. He was no less beautiful to her now. Once he had had silver-white hair and eyes like gray skies. This Jem had raven-black hair, curling slightly in the humid air, and dark brown eyes with glints of gold in the irises. Once his skin had been pale; now it had a flush of color to it. Where his face had been unmarked before he’d become a Silent Brother, there were two dark scars, the first runes of the Brotherhood, standing out starkly at the arch of each cheekbone.

If the question is “Was the the heavenly fire or becoming a Silent Brother that changed his hair and eye color?” the answer is the second one. That is why Brother Zachariah is always described as having dark hair. The yin fen is what turned his hair and eyes silver, and when it went away, so did the silver color.

Hi, Cassie! You have so many current projects (Tales from the Shadowhunter Academy, The Dark Artifices, The Last Hours, Magisterium), that it’s really hard to keep track of all of them. I know you don’t have set release dates for most of them, but could you please make an updated timeline of the book order, and when they might possibly be coming out? I can’t wait to read Lady Midnight! — buffylives

Sure. I went ahead and updated the timeline I posted earlier below, to reflect Shadowhunter Academy.

brookeelizaxo said: Hi Cassie! I love your books so so so sooo much! I finished City of Heavenly Fire and it was amazing. I was wondering when the rest of your novels were being released (TDA, TLH, TWP, etc)? Are there set dates or years for the releases? Thank you for such wonderful series! :)

Shadowhunter Chronicles:

City of Heavenly Fire wrapped up the Mortal Instruments series. The next installment of the Chronicles is The Dark Artifices, which takes place five years after CoHF. You can read about them here.

There are three Dark Artifices books: Lady Midnight, Lord of Shadows, and Queen of Air and DarknessLady Midnight is tentatively scheduled for release in late 2015 though it is not definite yet.

The Last Hours, the sequel series to The Infernal Devices, begins publishing shortly after Lady Midnight. You can read about it here. It’s about the children of the Infernal Devices characters.

Tales from the Shadowhunter Academy is a sort of follow-up to the Bane Chronicles, in that it is 10 e-book stories that follow Simon from his arrival at the newly re-opened Academy in Idris for Shadowhunter training to the day he Ascends. You can read about it here.

So the order of books is:

The Bane Chronicles print edition, November 11, 2014

Tales from the Shadowhunter Academy, starting early 2015

Lady Midnight (The Dark Artifices 1)

Chain of Gold (The Last Hours 1)

Lord of Shadows (The Dark Artifices 2)

Chain of Iron (The Last Hours 2)

Queen of Air and Darkness  (The Dark Artifices 3)

Chain of Thorns (The Last Hours 3)

That carries us through for quite a few years, so other than saying that the Shadowhunter Chronicles is intended to wrap up permanently with an installment called The Wicked Powers, I think that’s all I can say right now.


The Iron Trial, the first book in the Magisterium series, came out September 9, 2014. There will be an installment of Magisterium every September for the next four years.

The second book, The Copper Gauntlet, is scheduled for September 2015.

Hope that helps!


BOOK COVERS COME TO LIFE: Cassandra Clare’s books {the mortal instruments} (6/6)

So cool to see them all together.


What’s up with Grace and Christopher Lightwood being married in the family tree? I’m confused and worried! — timelord-amypond

There’s no reason to be worried!

The family tree is meant to be a ‘found object.’ Meaning that it is supposed to be created by a person, so it isn’t a piece of objective truth.

There are reasons for pretty much everything in the family tree. But some of the marriages are arranged/faked, some of the people marked as dead became mundanes/Downworlders, there’s a reason the Carstairs records have been destroyed, etc.

You can’t, honestly, predict the plot of The Last Hours by looking at the family tree. So even though it is a fun thing, don’t let it give you grief. By the end of the books, you will understand why even the things in it that are not true were written down as they are.
