The year is 1984 and space shuttle astronaut Tom Cabot is about to reenter Earth's orbit—only to crash-land two hundred years into the future.

His world is gone. In its place—the ruins of a civilization that made his century look primitive. Hovercars rust in the streets of shattered cities. Food replicators gather dust in Quick-Marts. Armies of autonomous killer droids still patrol the apocalyptic wreckage, somehow following orders from a world on another plane of existence.

And in the middle of it all—Wren. A fierce, suspicious hunter from a nomadic clan who thinks Tom’s a demon and would sooner put a knife to his throat than trust him. She's everything this brutal new world made: sharp, hard, and dangerously beautiful. Tom’s survival depends on Wren—her knowledge of the land and what he’s up against. Her survival hinges on his brilliant mind. Neither of them needs the tension that crackles every time they get too close—but neither of them can stop it.

With a rogue AI companion, a countdown to a celestial event that will change everything, and enemies converging from every direction, Tom and Wren must cross six hundred kilometers of scorched earth together to find the answers that just might save their lives.

If they don't kill each other first.
