"After her parents' divorce, 16-year-old Riley Grishin is forced to move from Portland, Oregon all the way to Little Brook, Maine, a small town that serves as the headquarters for Titan Technologies, an international tech laboratory. Having left her friends and father behind, Riley spends most of her days running through the woods with her dog Tigger, and eavesdropping on her classmates--in particular, the gorgeous, but very strange, Aspen Montehugh. On the night of the homecoming game, Riley wakes up to find her town on fire, terrorized by an unseen monster. Riley and Tigger have no choice but to pile into her pickup truck and flee. On the way out of town, they come across the only other survivor: Aspen. And now they're being followed by an SUV with blackout windows. She and Aspen embark on a cross country road trip, all the while pursued by men with guns, mad scientists, and the monstrous truth. Slowly, Riley realizes that something's not quite right with Aspen, which puts her feelings for her--and her own humanity--to the ultimate test"--
