Paper Towns

Quentin Jacobson has spent a lifetime loving the magnificently adventurous Margo Roth Spiegelman from afar. So when she cracked open a window and climbs into his life, dressed like a ninja and summoning him for a 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 engima, 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 the girl he thought he knew. . . .
