The place they were going—Ty had the address—was on Gill Street, Magnus had explained, in Limehouse. “Used to be a terrible neighborhood,” he said. “Full of opium dens and gambling houses. God, it was fun back then.”

Mark had looked immediately panicked.

“Don’t worry,” Magnus had added. “It’s very dull now. All fancy condos and gastropubs. Very safe.”

Julian would have forbidden this excursion, Kit was fairly sure. But Mark hadn’t hesitated—he seemed, far more than his brother, to regard Livvy and Ty as adult Shadowhunters who were simply expected to work like the others.

It was Ty who had hesitated for a moment, looking worriedly at his sister. Livvy seemed absolutely fine now—they were on the top level of the boat, open to the air, and she was raising her face into the wind with unabashed pleasure, letting it lift her hair and whip it around.

Ty was watching everything around them with that absorbed fascination of his, as if he were memorizing every building, every street. His fingers drummed a tattoo on the metal railing, but Kit didn’t think that indicated anxiety. He’d noticed that Ty’s gestures didn’t always correspond to a bad mood. Sometimes they corresponded to a good one: If he was feeling relaxed, he’d watch his own fingers make lazy patterns against the air, the way a meteorologist might watch the movement of clouds.

“If I became a Shadowhunter,” Kit said, to neither of the twins specifically, “would I have to do a lot of homework? Or could I just, sort of, start doing it?”

Livvy’s eyes sparkled. “You are doing it.”

“Yes, but this is a state of emergency,” said Ty. “He’s right—he’d have to catch up on some classes. It’s not as if you’re as ignorant as a mundane would be,” he added to Kit, “but there are some things you’d probably need to learn—classes of demons, languages, that sort of thing.”

Kit made a face. “I was really hoping I could learn on the job.”

Livvy laughed. “You could always go in front of the Council and make a case for it.”

“The Council?” said Kit. “How are they different from the Clave?”

Livvy laughed harder.

“I can see how your case might not be successful,” said Ty. “Though I suppose we could tutor you a bit.”

“A bit?” said Kit.

Ty smiled his rare, dazzling smile. “A bit. I do have important things to do.”

Kit thought of Ty on the roof the night before, how desperate he had seemed. He was back to his old self now, as if Livvy’s restoration had restored him, too. He rested his elbows on the rail as the boat chugged past an imposing fortress-like building that loomed over the riverbank.

“The Tower of London,” said Livvy, noticing Kit’s gaze.

“The stories say that six ravens must always guard the Tower,” said Ty, “or the monarchy will fall.”

“All the stories are true,” said Livvy in a soft voice, and a chill went up Kit’s spine.

Ty turned his head. “Wasn’t it a raven that carried Annabel and Malcolm’s messages?” he said. “I think that was in Emma and Julian’s notes.”

“Seems unreliable,” said Kit. “What if the raven got bored, or distracted, or met a hot falcon on the way?”

“Or was intercepted by faeries,” said Livvy.

“Not all faeries are bad,” said Ty.

“Some faeries are good, some are bad, like anyone,” said Kit. “But that might be too complicated for the Clave.”

“It’s too complicated for most people,” Ty said.

From anyone else, Kit would have thought that the comment was meant to be reproving. Ty, though, probably just meant it. Which was oddly pleasant to know.

“I don’t like what we’ve been hearing from Diana,” said Livvy. “About how Zara’s claiming she killed Malcolm.”

“My dad used to say that a big lie was often easier to carry off than a small one,” said Kit.

“Well, hopefully he was wrong,” said Livvy, a little sharply. “I can’t stand the idea that anyone thinks Zara and people like her are heroes. Even if they don’t know she’s lying about Malcolm, the Cohort’s plans are despicable.”

“It’s too bad none of you can just tell the Clave what Julian saw happen in the scrying glass,” said Kit.

“If they knew he’d gone to Faerie, he could be exiled,” said Livvy, and there was an edge of real fear in her voice. “Or have his Marks stripped.”

“I could pretend I’m the one who saw it—it matters a lot less if I get tossed out of the Nephilim,” Kit said.

Kit had meant to lighten the mood with an obvious joke, but the twins looked rattled. “Don’t you want to stay?” Ty’s question was direct and sharp as a knife.

Kit had no answer. There was a clamor of voices, and the boat jerked to a halt. It had docked at Limehouse, and the three of them hurried to get off—they were unglamoured, and as they pushed past several mundanes to get to the exit, Kit heard one of them mutter about kids getting tattooed way too young these days.

Ty had made a face at all the noise, and had his headphones on as they wove through the streets. The air smelled like river water, but Magnus had been right—the docks vanished quickly, replaced by winding roads full of massive old factory buildings that had been turned into lofts.

Ty had the map, and Livvy and Kit walked a little behind him, Livvy with her hand casually at her waist, where her weapons belt was hidden by her jacket. “He uses the headphones less when you’re around,” she said, her eyes on her brother, though her words were for Kit.

“Is that good?” Kit was surprised.

Livvy shrugged. “It isn’t good or bad. It’s just something I noticed. It’s not magic or anything.” She glanced sideways at him. “I think he just doesn’t want to miss anything you say.”

Kit felt an odd stab of emotion go through him. It surprised him. He glanced sideways at Livvy. Since they’d left Los Angeles, she’d done nothing to indicate she wanted to repeat their one kiss. And Kit had found that he didn’t either. Not that he didn’t like Livvy, or find her pretty. But something seemed off about it now—as if it were somehow wrong.

Maybe it was the fact that he didn’t know if he wanted to be a Shadowhunter at all.

“We’re here.” Ty had shoved his headphones down, the white band of them stark against his black hair. He alone among all the current Blackthorns had hair like that, though Kit had seen pictures in the Institute of their ancestors, some with the same dark hair and silver-gray eyes. “This should be illuminating. Shops like this have to abide by the Accords, unlike the Shadow Market, but they’re also run by specialists.” Ty looked enormously happy at the thought of all that specialized knowledge.

They had passed the wider thoroughfare of Narrow Street and were now on what was presumably Gill Street, across from a single open shop. It had dimly lit windows and the owner’s name spelled out in brass letters over the door. PROPRIETOR: F. SALLOWS. There was no description of what kind of shop it was, but Kit supposed that those who shopped there knew what they were shopping for.

Ty was already across the street, opening the door. Livvy hurried after him. Kit was last—cautious and a little less than eager. He had grown up around magic-sellers and their patrons, and was wary of both.

The inside of the shop didn’t offer much reason to improve his views. The frosted windows let in glare but not light. It was clean at least, with long shelves lined with some things he’d seen before—dragon’s teeth, holy water, blessed nails, enchanted beauty powders, luck charms—and quite a few he hadn’t. Clocks that ran backward, though he had no idea why. The wire-jointed skeletons of animals he’d never seen before. Shark teeth too big to belong to any shark on earth. Jar after jar of butterfly wings in explosive colors of hot pink, neon yellow, and lime green. Bottles of blue water whose surfaces rippled like tiny seas.

There was a dusty copper bell on the front counter. Livvy picked it up and rang it, while Ty studied the maps on the walls. The one he was staring at was marked with names Kit had never seen before—the Thorn Mountains, Hollow Town, the Shattered Forest.
