For Lilly, Hannah, and Griffyn, the playground was a sanctuary-a place of laughter and "monkey bar hands." But as they hit fourteen, the sanctuary begins to crumble. Lilly is trapped in the suffocating silence of her parents' bitter divorce, feeling like she's standing on a fault line that is about to swallow her whole. ​When a routine act of rebellion-skipping school to help a friend-leads to a split-second decision, the world tilts on its axis. A momentary lapse in judgment lands Lilly and Hannah in the back of a black sedan driven by a stranger with a chillingly calm demeanor. What began as an escape from their domestic lives becomes a desperate fight for survival. Outside the car, Griffyn and Ky are forced into a frantic, high-speed pursuit, leaning on an older friend and their own raw instincts to save the girls before the trail goes cold.
