“It’s not easy,” said Kira. “It never has been, and it never will be. Look at the hell we’ve gone through just to get this far—just to convince even a tiny portion of each species to work together. It’s always easier to die for your own side than to live for the other one. But that’s what we have to do: to live, day after day, solving every new problem and overcoming every new prejudice and building on every common ground we can find. Waging war was the easy part—making peace will be the hardest thing we’ve ever done.”

One of the East Meadow refugees spoke up; Heron thought she recognized him as the one called Marcus. “As important as it is that we, you know, stand around and breathe on each other, we should probably focus on getting the hell out of here. That little blown bridge isn’t going to hold them forever.”

“The rest of the humans are southwest of here,” said Samm, “on a narrow slip of land called Breezy Point.”

“That’s where we figured they’d go,” said Kira. “Have you talked to them?”

Samm shook his head. “We came in through Brooklyn, and since I didn’t know how else to find you, we went to the closest human stronghold, which was the JFK airport; there were a few stragglers there, and they told us where the humans were gathering. Sounds like most of the island managed to make it there—twenty thousand at least, maybe thirty. They didn’t know anything about you, though, so our plan was to go to East Meadow next, and that’s when we heard the gunfight. I didn’t know it was you until we found the front of your column and asked who was in charge.”

“We were glad to see you,” said Marcus, and Heron caught him glancing uncertainly at Kira. He didn’t sound as glad as he claimed to.

Heron dropped back, ignoring them as their conversation turned to the more mundane topic of what to do next, and how to do it. They had more than three hundred human refugees in Kira’s group, and seventeen miles to go before they could join the rest of the humans at Breezy Point. The Partial army would catch up to them, maybe not immediately, but inevitably. After this midnight chase had failed they were likely to wait before the next assault, gathering their forces and then coming down on the humans with overwhelming force. Kira’s little band was doomed, and every other human on this island, and Heron did not intend to be here when that doom arrived. Thirty thousand humans were impossible to hide, even with a handful of Partials to protect them.

But one Partial, and one human to protect her from expiration, could disappear forever.
