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 and a new day breaks, Q arrives at school to discover that Margo, always an enigma, has now become a mystery. She has disappeared. Q soon learns that there are clues in her disappearance . . . and they are for him. Trailing Margo's disconnected path across the USA, the closer Q gets, the less sure he is of who he is looking for.
