Maeve Chambers doesn't have much going for her. Not only does she feel like the sole idiot in a family of geniuses, she managed to drive away her best friend Lily a year ago. But when she finds a pack of dusty old tarot cards at school, and begins to give scarily accurate readings to the girls in her class, she realizes she's found her gift at last. Things are looking up - until she discovers a strange card in the deck that definitely shouldn't be there. And two days after she convinces her ex-best friend to have a reading, Lily disappears.
