Margo Roth Speigelman, le nom qui fait fantasmer Quentin depuis toujours. Alors, forcément, quand elle s'introduit dans sa chambre, un soir, pour l'entaîner dans une expédition vengeresse, il la suit. Mais au lendemain de leur folle nuit blanche, Margo a disparu. Quentin saura-t-il décrypter les indices qu'elle a laissés derrière elle ?

Quentin Jacobsen has always loved Margo Roth Spiegelman, for Margo (and her adventures) are the stuff of legend at their high school. So when she one day climbs through his window and summons him on an all-night road trip of revenge he cannot help but follow. But the next day Margo doesn't come to school and a week later she is still missing. Q soon learns that there are clues in her disappearance . . . and they are for him. But as he gets deeper into the mystery - culminating in another awesome road trip across America - he becomes less sure of who and what he is looking for.
