Caroline Lawson is three months away from freedom, otherwise known as graduation day. That's when she'll finally escape her rigid prep school and the parents who thought they could convert her to being straight. Until then, Caroline is keeping her head down, pretending to be the perfect student even though she is crushed by her family and heartbroken over the girlfriend who left for California. But when her best friend Madison disappears, she realises how little she knew of what her friend was up to. Caroline has some uncomfortable secrets about the hours before Madison disappeared, but they're nothing compared to the secrets Madison has been hiding.
