Mara Valentine is in control. She's a straight-A student, a strict vegan and she's heading to Yale in the fall. So when her hellraising sixteen-year-old niece, V, comes to live with the family, Mara is horrified. Even more so when she starts dreaming about cheese sandwiches every night and realizes she is falling for James, her boss. Unable to ignore these unfamiliar cravings, Mara starts to give into them a little and in doing so discovers her sexuality, redefines her relationship with her over-anxious parents, and realizes that V could in fact be a potential friend and ally.
