"Quentin Jacobsen has spent a lifetime loving the magnificently adventurous 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, 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 the girl he thought he knew" (Goodreads review).

Quite a mind-bending mystery, Green presents a cast of flaws and reveals that our flaws (and the recognition of them) allow us to see the humanity in each other. I love that Green tears down the trope of the manic pixie dream girl, transforming Margo from a plot device to a real character full of unlovable yet realistic qualities. Although I can see people demonizing Margo for her selfishness, at least she recognizes this in herself and is honest to her qualities.
