The journey through the rift becomes even rockier as the survivors are forced to take to the water, crossing a vast lake on improvised boats.
But halfway across, they discover something is tracking them from deep beneath surface, a colossal monster that's stranger--and larger--than anything they've encountered yet.
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).
