From a National Book Award winner, plane crash survivors must cross a body of water protected by a dangerous predator in order to find hope of rescue. The journey through the rift becomes even rockier as the survivors are forced to take to the water, crossing a vast deep-water basin on improvised boats. To make it, Molly and the others must work together, but a rift of a different kind is forming among the survivors. If they aren't careful, it could eat them alive. New York Times–bestselling author and National Book Award winner M.T. Anderson (Feed) helms this heart-pounding voyage in the epic survival series begun by Scott Westerfeld (Uglies).
