Quentin “Q” Jacobsen has lived next door to Margo Roth Spiegelman all his life, but they haven’t been close for years when she invites him to spend a night settling scores with her cheating boyfriend and lame friends. The next day, when Quentin thinks they might start to be close again, Margo disappears, but she leaves clues that lead Q and his friends on a confusing and rewarding chase to track her down, and to track down her—and their—futures in the process.
