Paper Towns

Quentin Jacobsen has spent a lifetime loving the magnificently adventurous Margo Roth Spiegelman from afar. So when she cracks open a window and climbs back 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. But Q soon learns that there are clues — and they’re for him. Urged down a disconnected path, the closer he gets, the less Q sees of the girl he thought he knew.
