And that wasn’t the only thing that Mariel had known before she died. There were also the other secrets: Rylin’s, and Avery’s, and Watt’s. The secrets that Leda told her in a drug-fueled haze. If the police kept digging, they might discover Mariel’s connection to the others too. They were in danger, and it was her fault.

She was going to have to see them again, she realized. All of them. Even Watt.

WATT

YOU’RE NERVOUS.

I’m not nervous, Watt insisted, then realized that he was perched on the very edge of Avery Fuller’s couch. He scooted back against the pillows self-consciously.

Okay, he told Nadia. Maybe a little nervous.

When Leda flickered him last night, Watt had practically slid out of his desk chair in shock. He almost thought the message was some kind of twisted practical joke from Nadia. He hadn’t been expecting to hear from Leda anytime soon—really, anytime ever—given the bleak finality of their good-bye last year.

Then Watt realized that it was a group message, and the other two recipients were Avery and Rylin. We need to talk—in person, Leda had written. I think we’re all in danger.

And despite the gravity of the situation, despite the fact that he should probably be concerned about whatever Leda had discovered, Watt couldn’t help feeling a fragile hope ballooning in his chest. He was going to see Leda again.

He’d shown up early to Avery’s apartment, hoping that he might catch Leda for a moment alone; after all, she was the one who’d summoned them all to this group meeting. But she hadn’t yet arrived. Watt just sat there silently, ignoring Avery’s pointed glances, trying to figure out what the hell he was going to say. How did you greet the girl you loved when you hadn’t seen her in eight months—when her last words to you were If you care about me at all, you’ll leave me alone?

He cast his gaze nervously around the room, all brocade carpets and blue-patterned wallpaper and carved antiques that looked as if they’d been shipped straight from Versailles. For all Watt knew, maybe they had. He’d forgotten how imposing it was simply to get this high: switching on the 990th floor to the private elevator that opened onto the Fullers’ landing, then stepping through that massive two-story entryway. He’d felt a bit like Hercules climbing the staircase of the gods to Mount Olympus.

Now here he was, in the fabled sky island, the bright human aerie perched atop the greatest structure in the world. Watt glanced out the floor-to-ceiling windows, the flexiglass so impossibly clear that it looked like it wasn’t there at all. He felt like he could stretch out his hands and brush the sky. What was it like for the Fullers, having no neighbors except those below them? Didn’t it feel strange that their only connection with the rest of the city was the opening to their private elevator shaft?

His head darted up at the sound of the doorbell, but then he realized that of course Leda wouldn’t need to ring the doorbell at all. She was on the preapproved entry list here.

“I thought we were done with all this.” Rylin Myers sank into the opposite armchair.

“I thought it was over too. A long time ago.” The sleeve of Avery’s sweater dress fell forward as she reached for a glass of lemon water. A platter of snacks was arranged on the coffee table before them, completely untouched.

How like Avery to provide refreshments at a time like this. Yet Watt couldn’t help thinking that it was oddly comforting, as if Avery’s unobtrusive hospitality was helping diffuse the tension.

He’d almost forgotten that when he first met Avery, he’d thought he was infatuated with her. But after dating Leda—after realizing what it really felt like to fall for someone—Watt knew that all he’d felt for Avery was a crush. He and Avery were much better off this way, as occasional friends.

He heard footsteps again, and before he could figure out what his first words to her would be (Something witty, Nadia, help!) Leda stepped into the living room, knocking all the air from the immediate vicinity.

She was even thinner than before, draped in a black turtleneck sweater, and her hair was cut short. It drew attention to the stark architecture of her face.

Leda’s eyes automatically rose to meet his. For a moment there was no one in the room but the two of them. Watt swallowed against the maddening flood of old tendernesses and love and frustrations that rose up in him.

She was really here. For the first time in months, she was here, and Watt couldn’t believe it; he felt as if he’d taken an adrenaline boost, slapped a million caffeine patches over every last inch of his skin. It was as if he’d been in a trance these long months without Leda, and seeing her again had struck him violently back to life.

“I would apologize for being late, except I think you’re all early,” she said smoothly, taking a step forward. Watt had forgotten the way she moved, as if every motion began in her warm, dark eyes, and flowed unbroken all the way to her ballet flats. She sat down next to Avery and crossed one leg over the other, only the slight jangling of her foot betraying her anxiety.

“We’re early because your message was so terrifying and vague!” Rylin cut in. “What’s going on?”

“The police are investigating Mariel’s death.”

There was a beat of collective silence at Leda’s announcement. Avery twisted her hands in her lap. Rylin’s eyes were wide with horror.
