“But we can’t kill them, either,” said Dominic. He appeared in the doorway behind Uncle Mike. His face was set in a blank, expressionless mask. It didn’t waver as he looked past the heads of the Covenant agents to me, filthy, naked, and bleeding all over the warehouse floor. “If we kill them, the Covenant sends more.”

“We win,” said Robert.

Istas squeezed Margaret’s hand. Margaret yelped, unable to help herself. “I am not so sure of that,” said Istas. “There is a difference between ‘living’ and ‘retaining all your limbs.’”

“They can’t leave,” said Uncle Mike. “They know who Verity is. It’s not safe to let them go.”

“So they can’t live and they can’t die.” It was taking everything I had just to keep myself upright. “Oh, and here’s one more for you: Dominic can’t stay here if we send them home. They’d never forgive another defection.” There was no way to win. There was no way to get out of this with everyone still standing.

“No. But they might be willing to bury a traitor.” Dominic stepped around his former colleagues and crossed to where I was standing. He took the gun from my hand, aiming it at Robert as he slid an arm around my waist, holding me up. I let myself sag into him.

Then I realized what he’d just said. “What? No! No. We’re not going to kill you.” I wanted to pull away and glare at him. I didn’t have the strength.

“I wasn’t going to ask you to,” said Dominic. “Sarah?”

“I’m here.” Sarah stepped up behind Uncle Mike, moving into the room on silent feet. “Istas, let go of Margaret’s hands. Robert’s anti-telepathy charm is attached to his medal of St. George. Take it off him.”

“Yes,” said Istas. She released Margaret—although she didn’t release Margaret’s gun, and from the way Margaret groaned as Istas yanked it away, she broke at least one of Margaret’s fingers in the process—and turned toward Robert. To his credit, he didn’t flinch when Istas reached for his throat with her vast, taloned paw. The chain on his medal snapped easily when she pulled on it. Istas looked at the medal curiously for a moment, then shrugged and tucked it into the neckline of her dress.

“Sarah . . .” I said.

“It’s all right, Verity.” She smiled at me, uncertainly. “I can do this.”

“I don’t know . . .”

“We have no choice,” said Dominic softly. He tightened his arm around me. “They have to live. I have to die. I can’t let them endanger you, or your family. This is the only way.”

“But Sarah . . .”

“Trust her,” said Dominic.

I closed my eyes. “Okay.”

Cuckoos are natural memory manipulators. It’s part of how their power works. They fit into the world without leaving a seam, and that means they have to insert themselves, retroactively, into the lives of every person they meet. It’s an autonomic function most of the time, something that just happens around them, as easy and as natural as breathing. Sarah spent her days working to keep that very thing from happening; she wanted to be known and cared about for who she really was, and not because everyone she met decided that she was their long-lost sister, daughter, or best friend from college.

Even autonomic functions can become intentional, if you’re willing to work for it. I opened my eyes to see Sarah standing in front of Margaret and Robert, her eyes glowing such a brilliant white that it actually chased the black spots away from the edges of my vision. Margaret looked terrified. Robert looked resigned, like this was the fate he had been preparing himself for since the day he reached American soil.

“You’ll pay,” he said, in a calm, quiet tone. “We found you once, and we can find you again. Eventually, your whole stinking family will have to pay for your crimes against the Covenant, and against humanity.”

“Maybe that’s true,” I said, letting myself slump against Dominic. “But you know what? You won’t be the ones to come looking for us.”

“Hold them up,” said Sarah. I think I’m the only one who heard the tremor in her voice.

Istas grabbed Robert while Uncle Mike lowered his crossbow and grabbed Margaret. Sarah reached out and touched their foreheads, making skin contact. Skin contact always made it easier for her. The Covenant agents went limp.

That seemed like a good idea. I couldn’t feel my feet anymore, and I was so tired. I stopped fighting to keep myself upright at all. Staying awake and on my feet didn’t matter. We’d done it. The Covenant didn’t know—wouldn’t know—that the family survived. There would be no purge of Manhattan. We’d won, and that meant that I could rest.

The last thing I heard was Dominic shouting my name. Then there was nothing but the white glare from Sarah’s eyes, chasing away the shadows, and I fell into the light . . .

. . . only to fall back out again as Dominic shoved me away, grabbing the gun from my hand in the same motion (didn’t he already have my gun? Something was wrong, and I couldn’t tell what it was anymore . . .). Sarah was on the floor, clear fluid leaking from a hole at the center of her forehead, and Margaret was somehow free, her own gun aimed at Dominic’s chest. “Traitor!” she shouted, and fired.

For some reason, the servitors were gone. For some reason, nothing moved to stop her when she pulled the trigger. Something should have stopped her. Instead, Dominic staggered back, making a sharp barking noise as the bullet slammed through his collarbone. Then he raised my gun and fired three times, aiming for Margaret, who ducked easily out of the way. One bullet went into Uncle Mike. The other two went into Istas. I knew from past experience that two bullets weren’t going to do much but slow her down.

Slowing her down was more than enough. The force of the bullets knocked her backward and allowed Robert to break free. He spun around, pulling a knife from his belt, and drove it into her throat. Istas keened like a wounded animal, and fell. And all this before I could hit the floor.

I landed hard, my head bouncing off the wood before I managed to catch myself. I raised my head, squinting, in time to see Margaret shoot Dominic again. This time, her aim was better, befitting a Healy girl: she grouped her shots at the center of his chest, three holes appearing in the fabric of his shirt. He looked surprised. Then he fell, too.
