The Lost Book of the White is the upcoming second book of The Eldest Curses trilogy, co-written by Cassandra Clare and Wesley Chu.


Magnus Bane and Alec Lightwood are settling into domestic life with their son Max when the warlocks Ragnor Fell and Shinyun Jung break into their loft and steal a powerful spell book. Realizing that Ragnor and Shinyun are being controlled by a more sinister force, Magnus and Alec set out to stop them and recover the book before they can cause any more harm. With the help of Clary Fairchild, Jace Herondale, Isabelle Lightwood, and Simon Lovelace (who is fresh from the Shadowhunter Academy), they track the warlocks to Shanghai.

But nothing is as it seems. Ragnor and Shinyun are working at the behest of a Greater Demon. Their goal is to open a Portal from the demon realms to Earth, flooding the city of Shanghai with dangerous demons. When a violent encounter causes Magnus's magic to grow increasingly unstable, Alec and Magnus rally their friends to strike at the heart of the demon's power. But what they find there is far stranger and more nefarious than they ever could have expected…[3][4]

Teaser #1

Now Magnus watched Alec walk toward their bed, safe and home and well-beloved, and he felt the last of the tension slip from his body. He could sleep again, he thought. It had been a while since they slept in their bed together, at the same time. Too long. He rolled his shoulders, sighing, and Alec's eyes followed the movement.

"I'm not tired," claimed Alec, clearly lying. "Are you tired? Or would you want to—stay awake?"

Oh. It had been a while for a few things.

Too long.

Magnus leaned in across the bed and lied, his voice soft and delighted: "I'm not tired."

Alec was already leaning in to him, his lean warrior's body stretched out on the bed and curving toward Magnus. They met halfway, the kiss moonlight soft at first. Magnus was smiling. Alec's warm mouth curved, after a moment, into an answering smile. Moonlight changed to starlight, a feeling like points of brightness coming to shining life all through Magnus's body.

Magnus separated reluctantly from Alec to help Alec slide off his worn T-shirt. Magnus dropped the T-shirt by the side of the bed, and began to draw his own rings from his fingers.

"Hey," Alec murmured, eyes shining in the low light, voice husky. "Leave them on."

It had been much too long.

"All right," Magnus whispered back. "Anything you want."

"Anything?" said Alec.

Magnus reached out and stroked the angelic rune traced against of Alec's throat, and felt Alec swallow under the light pressure of Magnus's fingers and the metal of his rings. Then Magnus clasped the nape of Alec's neck and drew him in for another kiss. His free hand glided up the arch of Alec's back, rings stuttering along his spine. His palm slid up to his shoulderblades, mapping the well-known and always wonderful stretch of soft skin and scars.

Alec broke the kiss with a gasp, and leaned his head down on Magnus's shoulder, tucking his face into Magnus's neck for a moment. He slid the robe off Magnus's shoulders, and as the silk slid away he kissed the bared brown skin. The press of his mouth was tender as well as passionate, every move of Alec's always so utterly sincere.

"Anything," said Magnus, and meant it with all his heart. "What do you want?"

"Everything," Alec mumbled. "You."

" 'Everything' and 'me' are not the same thing," Magnus murmured.

"They are to me," said Alec.

He kissed him again, kissed away the startled look Magnus knew he was wearing, still caught off guard by Alec Lightwood, still wondering if this could possibly be for him. This kiss went as deep as the first one tonight had been soft, and as they kissed Alec tumbled back on the silk pillows and pulled Magnus down against him.

Magnus nuzzled the rune on the side of Alec's neck, then kissed the hollow at the base of his throat, and felt the shiver run through Alec's body beneath him.

Then a scream broke the air.

Teaser #2

Alec took note. “I don’t much like being looked at like the enemy here,” he said. “We’re all on the same side, Shadowhunters and Downworlders.”

Jace quirked an eyebrow. “I believe the Clave’s official position is that we are on opposite sides.”

“It’s ridiculous,” said Clary. “How many faeries were actually on Sebastian’s side in the war? The Queen, her court—it must be a tiny percentage of them. But we’ve punished them all.”

“They’ve punished them all,” said Simon. “We haven’t done anything. We tried to prevent the Cold Peace.”

“As long as we can explain that to each of them individually, I’m sure we’ll be fine,” said Jace.

“Maybe we could get t-shirts made,” Simon agreed. “’We Tried to Prevent the Cold Peace.’”

Teaser #3

Magnus found his robe, blinked the sleep from his eyes, and went into the kitchen, where Jace Herondale was pouring coffee into Magnus’s “I’m Kind of a Big Deal” mug.

“Don’t you have your own coffeepot?” Magnus said blearily.

Jace, blond hair in its usual, preternaturally excellent state,flashed him a winning smile that Magnus was not prepared to deal with before he too had some coffee. “I hear you got stabbed by a weird Norwegian thorn,” Jace said. “Also, do you have any soy milk?Clary’s doing a whole soy milk thing now.”

“What are you doing in my apartment?” said Magnus.

“Well,” said Jace, now rummaging in the fridge, “I’d like to think I’d be welcome anytime, what with my close relationship with all three of you. But in this case, Alec called us. Said something about Shanghai.” ​“Who is us?” Magnus said suspiciously.

Jace waved his coffee cup around. “Us! You know. All of us.”

“All of you?” Magnus repeated. He held up a hand. “Wait. Stop. I am going to go put on something more substantial than a kimono. You are going to use your angelic powers to pour me as large a mug of black coffee as you can find, and I will be right back, and then we can talk about terrible concepts like who ‘all of you’ are, or what Alec told you about last night.”

When he returned to the living room, now suitably dressed, he found Alec, arms folded, looking long-suffering. In the far corner of the room, next to the ceiling, Max floated, tumbling in the air. He didn’t seem to be in peril—indeed, he was yelling “Wheeeeeeeeeee” and appeared to be having an excellent time. Under him, Clary Fairchild and Isabelle Lightwood attempted to nudge him back to the ground with a broom handle. With her free hand, Clary was waving a red braid, trying to get Max interested as though he were Chairman Meow. Max was upside-down and obviously feeling good about it. Everyone else was in t-shirts and jeans, but Isabelle, of course, had shown up in a fitted black sweater over a tiered velvet maxi skirt. She was one of the few people who could occasionally make Magnus feel underdressed.

Teaser #4

They met Magnus at the point where the pedestrian part of the road ended and car traffic began. Magnus’s hair was, strangely, soaking wet, and spiked angrily up above his head. His clothes were dry, but they were not the same clothes he had been wearing when they went through the Portal. Alec was a little disappointed—he loved Magnus in a suit—but Magnus had perhaps wisely chosen to blend in, in black jeans and t-shirt and a black leather motorcycle jacket. He looked like a sexy urban ninja. Alec was in favor of it.

He swept up to Alec, put his arms around his head, and kissed him. Alec blinked in surprise and kissed him back, passionately. But closed-mouthed-ly. He was standing in front of his sister and his parabatai and his parabatai’s girlfriend and her parabatai. He had to draw a line somewhere. But he did kiss Magnus back as strongly as he was able; he was relieved, he could feel his body relax.

“I guess you also didn’t go to the Institute,” said Clary, when a significant amount of time had passed.

Magnus broke the kiss.

“Is it all right? For two men to kiss in a crowded street in Shanghai? I don’t know if I’d kiss you that way in Times Square,” said Alec.

“Darling,” Magnus said quietly, “we’re invisible.”

“Oh,” said Alec. “Right.”

“I did not go to the Institute, no,” said Magnus to Clary. “I went to ten or so meters above the Huangpu River.” He saw Alec’s look of alarm. “Then a few seconds passed, and I was in the Huangpu River.”

“What did you do?” said Jace.

“I tumbled through the air gracefully and landed on my feet on the back of a friendly porpoise,” said Magnus.

“That is very believable,” said Simon.

Magnus waved his hand. “That is how I wish you to think of me. Riding a porpoise into shore, and straight to join you. But no, I did not go to the Institute. I don’t understand it. That’s two Portals in a row that have gone wrong, in ways Portals should not go wrong. How did we get split up?”

Teaser #5

Magnus looked up at the Portal. He could see nothing through it, only clouds so dark they were almost black. Long silken threads were emerging from points within it, and down those threads slid dark gray spheres the size of large dogs. As they descended, they unfolded to reveal themselves to be—no surprise, given the day he’d had—huge spiders.

He shot Alec a glance. Alec wasn’t the biggest fan of spiders…

Teaser #6

“Huh. What’s with the, uh, flail, Jace?” Alec  asked.

“It’s a morning star,” said Clary, in deeply mournful tones. 

“Morning stars don’t have chains,” said Alec. “It’s a flail.”

“He wants us to call it a morning star,” said Clary, even more gloomily. “You’re not even a Morgenstern,” she said to Jace. “I’m a Morgenstern.”

“I’m still closely associated with the name,” Jace insisted. “I was just feeling like—can I pull off having a morning star as my signature weapon? Is it me?”

“Of course you can, honey,” said Clary. “Look,” she added to Alec. “I see the concern on your face. I figure we let this run its course for a week or so. If it doesn’t burn out by then we can step in.”

“Fair enough,” said Alec.

Teaser #7

Alec was getting a little frustrated. He’d called Catarina and asked if she could look after Max for a couple of days, only to find out that she was working double shifts at the hospital and would barely be home (though she did agree to stop in and feed Chairman Meow in the evenings). He’d called Maia, who turned out to be hosting friends of Bat’s. He’d considered, but rejected, calling Lily. Lily often spoke of how Max was “so delicious” that she just wanted “to eat him up,” and while Alec trusted Lily, he was not completely sure she was speaking figuratively.

“What about your mother?” Magnus said. He had put Max into an iridescent magical bubble and was rolling him around the bed- room while Alec fetched suitcases from the back of their closet.

“What? No,” Alec said. He watched Max for a moment. “Is he in a magical hamster ball?”

“No! Well, kind of, yes,” said Magnus. “He likes it. Why not your mother?”

“This kid floats up to the ceiling sometimes,” said Alec. “He sets a blanket on fire in his sleep every three weeks or so.”

“Another advantage of the magical hamster ball,” said Magnus. “Magic shield. I didn’t want Max knocking out the neighbors’ cable again.”

“Well, my mother doesn’t have a magical hamster ball,” said Alec.

Magnus rolled Max out into the hallway, to squeals of delight, and called back, “She’s a Shadowhunter! She’s supposed to be able to handle warlocks. She raised you!” He ducked his head back into the bedroom and raised his eyebrows. “She raised Jace.”

“All right!” said Alec, laughing. “You win. I’ll call her.”

Teaser #8

“I googled it,” Jace said, to Alec’s surprise. “While we were getting our stuff together.”

“You,” said Alec, “googled it?”

“Yeah,” said Jace. “It sounded Norse, so I went to the library and looked it up in the Saga Concordances. That’s googling, right?”

“More or less,” said Simon.

Teaser #9

Clary suddenly grabbed his arm and said, in a quiet but intense tone, “I need to talk to you for a moment.”

Magnus regarded her. It was so strange to see her now, a proper adult. For years, she had been a quiet, wide-eyed child whom he’d met over and over for the first time. She knew nothing of the Shadow World—and it had been Magnus’s job to make sure that remained true. And so when her mother would bring her over, she always had the same reaction—awe, uncertainty. Each time, she noticed his eyes, luminous and slit-pupiled—each time, he expected her to be frightened, but she was only ever curious. When she got old enough, she would ask him, “Why do you have cat eyes?” He got to try out plenty of responses.

“I traded them with my cat. Now he has human eyes.”

“The better to see you with, my dear.”

“Why do you not have cat eyes?”

It was strange to know that Clary didn’t share those memories.

To have watched someone grow up without them remembering it. Until, of course, the day he saw her at Chairman Meow’s birthday party, surrounded by New York’s Shadowhunters, and without warning, transformed into the warrior she had been born to be, already the spitting image of Jocelyn at her age.

Now she looked uneasy, as though she was thinking about how to deliver bad news. A few years ago she would just have blurted it out, but now she was his friend and she was concerned about his feelings. It was nice, but strange.

She said, “I had a dream about you, this morning. Just before Alec’s call woke us up.”
