“They’re there,” Erich shouted back, gesturing with his bad arm and holding on to the strap with his good. “They’re all there. It’s just there’s not as many as there were last week. And more than there are going to be.”

Over Boston, someone fired a missile toward them from the roof of a commercial shopping district, and the copters shot it down. The sky to the east was the low bruise-dark that made Amos think of storm clouds. In the west, the sunset was the color of blood.

“We gonna have trouble with the rotors icing up?” Amos asked the pilot, but he didn’t get an answer.

They set down at an airfield a few klicks south of the lake, but Amos got a look before they landed: low hills holding the water like it was being cupped in a massive palm. There were maybe a dozen islands scattered across the lake, some as crowded with buildings as the shore, others with little tame forests if someone rich enough for the luxury lived there. The landing platform was a square of floating ceramic with red and amber lights still blinking for visual landings.

When they actually got to the water’s edge, it wasn’t as pretty. The water stank of dead fish and a coating of ash lay across the surface like someone had sifted chalk dust over the whole place. Erich’s people waded in up to their thighs and dropped three packages that unfolded into hard, black pontoon boats. By the time they started toward the enclave on Rattlesnake Island, the sky was a perfect black. No stars, no moon, no backsplash of light pollution. The night was like sticking his head in a sack.

They spun to the north side of the island where a wide bridge on a coated steel pier ran out toward the launching pad. Hangars and boathouses encrusted the shore, boxes for the toys of the wealthy as big as basic housing blocks for a thousand people. The pontoon boat they were in surged forward over the chop of the water. The boathouse they chose was painted bright blue, but outside the circles of their lights, it could have been anything. It only took a minute to find the keypad on a pole that poked up from the dark water. Peaches leaned over, stretched her thin arm, and tapped out a series of numbers. For a second, it looked like it hadn’t worked, then the boathouse doors silently rose and automatic lights came on. The interior was all wood paneling, rich red cedar, and enough room for a tennis court. An angry barking came out from the darkness as they steered inside.
