He looked at her through the haze. His mouth tasted bitter. “Are you a Shadowhunter?”

“I am not,” Tessa Gray said with a surprising firmness. “But you are.” She reached her hand down toward him. “Come now,” she said. “On your feet, Christopher Herondale. We’ve been looking for you a long time.”

“Say something,” Emma said. “Please.”

But the boy in the passenger seat next to her didn’t speak. He was looking out the window toward the ocean; they had made it all the way to the coast highway without Kit saying a word.

“It’s all right,” Tessa said from the backseat of the car. Her voice was gentle, but then, her voice was always gentle. “You don’t need to speak, Christopher.”

“No one calls me that,” said Kit.

Emma jumped a little. Kit spoke in a monotone, staring out the window. She knew he was a little younger than she was, but more from his demeanor than anything else. He was quite tall, and his moves back at his house, fighting the Mantid demons, had been impressive.

He wore bloody jeans and a blood-soaked T-shirt that had probably once been blue. The ends of his pale blond hair were sticky with ichor and blood.

Emma had known there was trouble the moment she’d arrived at Johnny Rook’s. Though the house looked the same, though the door was closed and the windows shuttered and quiet, she’d felt a lack of the magical energy that had been apparent when they’d been there before. She’d glanced back down at the text message on her phone and drawn Cortana.

The inside of the house looked as if a bomb had gone off. It was clear the Mantids had come from the ground under the house—demons often traveled beneath the earth to avoid daylight. They had burst up through the floorboards; ichor and blood and sawdust were everywhere.

And Mantids. They looked far more grotesque in Johnny Rook’s living room than they had on the cliff tops of the Santa Monica Mountains. More insectile, more monstrous. Their razored arms sheered through wood walls, slashed apart furniture and books.

Emma swung Cortana. She sliced one Mantid apart; it disappeared with a screech, leaving her view of the room unobstructed. Several of the other Mantids were splashed with red, human blood. They circled the remains of what had been Johnny Rook, in pieces on the floor.

Kit. Emma looked around wildly, saw the boy crouching by the stairs. He was unharmed. She started toward him—just as he seized up a chair and smashed it down over a Mantid demon’s head.

Only training kept Emma from stopping in her tracks. Human children didn’t do that. They didn’t know how to fend off demons. They didn’t have the instinct—

The door behind her blew open, and again only her training kept her from halting in surprise. She managed to sever the head of another Mantid demon, slicking Cortana’s blade with ichor, even as Jem Carstairs raced into the room, followed by Tessa.

They had plunged into the battle without a word to each other or to Emma, but Emma had exchanged a glance with Jem as they fought, and knew that he wasn’t surprised to see her. He looked older than he had in Idris—now closer to twenty-six, more a man than a boy, though Tessa looked just the same.

She had the same sweet expression Emma remembered, and the same kind voice. She had looked at Kit with love and sadness when she had gone over to him and held out her hand.

Christopher Herondale.

“But Kit is short for Christopher, is it not?” Tessa asked now, still gently. Kit said nothing. “Christopher Jonathan Herondale is your true name. And your father was Jonathan, too, right?”

Johnny. Jonathan.

There were a thousand Shadowhunters named Jonathan. Jonathan Shadowhunter had founded the whole race of Nephilim. It was Jace’s name as well.

Emma had heard Tessa back at the house, of course, but she still couldn’t quite believe it. Not just a Shadowhunter in hiding, but a Herondale. Clary and Jace would need to be told. They would likely come running. “He’s a Herondale? Like Jace?”

“Jace Herondale,” Kit muttered. “My father said he was one of the worst.”

“One of the worst what?” Jem asked.

“Shadowhunters.” Kit spat the word. “And I’m not one, by the way. I’d know.”

“Would you?” Jem’s voice was mild. “How?”

“None of your business,” Kit said. “I know what you’re doing. My dad told me you’d kidnap anyone under nineteen with the Sight. Anyone you thought you could make into a Shadowhunter. There’s barely any of you left after the Dark War.”

Emma opened her mouth to mount an indignant protest, but Tessa was already speaking. “Your father said many things that weren’t true,” she said. “Not to speak ill of the dead, Christopher, but I doubt I am telling you anything you don’t already know. And it is one thing to have the Sight. It is another thing to fight off a Mantid demon with no training.”

“You said you’ve been looking for him?” Emma asked, as the run-down Topanga Canyon Motel flashed by, its smeared windows dull brown in the sunshine. “Why?”

“Because he is a Herondale,” said Jem. “And the Carstairs owe the Herondales.”

A faint shudder went through Emma. Her father had spoken the same words to her, many times.

“Years ago, Tobias Herondale was convicted of desertion,” said Jem. “He was sentenced to death, but he could not be found, so the sentence was carried out on his wife instead. She was pregnant. A warlock, Catarina Loss, smuggled the baby to safety in the New World.”
