Growing up in privileged, Manhattan social circles, Caggie's life should be perfect, and it almost was until the day that her younger sister drowned when Caggie was supposed to be watching her. Stricken by grief, Caggie pulls away from her friends and family, only to have everyone misinterpret a crucial moment when she supposedly saves a fellow classmate from suicide. Now she's famous for something she didn't do and everyone lauds her as a hero. But inside she still blames herself for the death of her sister and continues to pull away from everything in her life, best friend and perfect boyfriend included. Then Caggie meets Astor, the new boy at school, about whom rumours are swirling and known facts are few. In Astor she finds someone who just might understand her pain, because he has an inner pain of his own. But the more Caggie pulls away from her former life to be with Astor, the more she realises that his pain might be darker, and deeper, than anything she's ever felt. His pain might be enough to end his lifeand Caggie's as well.
