Quentin Jacobsen has spent a lifetime loving Margo Roth Spiegelman from afar. So when she cracks open a window and climbs into his life—dressed like a ninja and summoning him for an ingenious campaign of revenge—he follows. After their all-nighter ends, Q arrives at school to discover that Margo has disappeared. But Q soon learns that there are clues—and they're for him. Urged down a disconnected path, the more Q nears, the more he sees the Margo he thought he knew is a myth.
