Nandita glared back at her, but after a moment of silence she spoke. “Before the Break there was a government laboratory on a tiny island off the eastern tip of this one, the Plum Island Disease Research Center. Being separated from the rest of the continent made it the only safe place to study the most contagious organisms, but it turns out that same isolation saved it when the rest of the world fell apart. It has its own power source, its own air and water recycling system, and a hermetically sealed interior—it hasn’t fallen apart the way everything else has. That’s where I made this.” She held up the hand-sized leather bag that hung around her neck, containing the small glass vial with a chemical trigger; the trigger that would release . . . something inside Ariel’s and Isolde’s bodies. Nandita had thought it was the cure for RM, but given everything unexpected that had happened with Khan, they could only wonder. “If there’s any facility in the world where I can study and cure Khan’s illness, it’s there.”

Ariel found herself instinctually assuming that Nandita must have other motives as well, but she didn’t have time to dwell on it. Isolde entered the room, and Khan, in a rare moment of surrender, was passed out from fatigue, asleep on her chest. Isolde looked just as exhausted.

Ariel looked back at Nandita, fixing her with her stare. “Can you actually save him?”

“I will stop at nothing.”

They stared at each other, sizing each other up. Ariel wondered what the old woman was thinking, what she was reading in Ariel’s face and attitude.

“If you can really help him,” said Ariel, “then I’ll stop at nothing to help you do it.”

And as soon as he’s safe, I’ll kill you.

CHAPTER SEVEN

General Shon, leader of the Partial invasion force, climbed down from his horse in the yard outside the Dogwood outpost. He handed the reins to his assistant, Mattson. The human Defense Grid had used Dogwood to patrol East Meadow, keeping threats at bay, and Shon now used it for the opposite purpose of keeping the humans contained inside the city. As the most remote outpost, it was also a handy place to keep certain things he didn’t want anyone, human or Partial, to find. The link data in the yard crackled with anxiety—Shon could feel edginess and uncertainty in the soldiers, just like the rest of the army, but here they were outright terrified, and with good reason.

The humans, it seemed, had released a biological weapon, and Dogwood was where Shon had been keeping the corpses of his Partial brethren who’d died from the disease.

“Are you sure it’s safe here, sir?” asked Mattson.
