Quentin Jacobsen has spent a lifetime loving the magnificent Margo Roth Spiegelman from afar. So when she cracks open a window and climbs back into his life—summoning him for an ingenious campaign of revenge—he follows. When their all-nighter ends and a new day breaks, Margo has disappeared. But Quentin soon learns that there are clues—and they're for him. Embarking on an exhilarating adventure to find her, the closer Quentin gets, the less he sees the girl he thought he knew. John Green crafts a brilliantly funny and moving coming-of-age journey about true friendship and true love.
