For fans of SILO and THE HUNGER GAMES, from the cult-favorite author of the EXPONENTIAL APOCALYPSE series. After a secret rendezvous goes fatally awry, store-crossed lovers Rhea and Wren, sixteen-year-olds from opposite sides of the last truck stop in existence, find themselves hunted and on the run, forced to survive in the post-utopian wreckage of an alien-blighted civilization. They'll need to face down the impossible threats of a neverending desert, the atomic insects and sandstorms and the barren nothingness of a world rusted sharp, in search of a city that shouldn't be. The nights are long and the odds are bad, but Wren and Rhea wouldn't have it any other way. They're finally free, reveling in being alone, and together. But happiness is never easy at the end of everything, and soon enough - and with some unexpected help - the teenagers stumble upon a series of cascading discoveries that upend everything they thought they knew, leaving them reeling, reconsidering, and forced to reckon with what they owe the ones they left behind.
