Fifteen-year-old Daisy Doyle's life reads like a modern day tragedy. In the midst of nursing her already broken heart after a disappointing breakup with her first real boyfriend, Daisy receives a second and even more devastating blow. Denny, her youngest brother has disappeared. The police aren't convinced that he's truly missing, but the tiny hairs standing up on the back of her neck tell her otherwise. Daisy, who has always been emotionally fragile, officially comes unhinged as her once nearly perfect life and family begin to unravel. She hadn't planned on taking her own life, but when she snaps at school and runs out in front of a bus, almost accidentally killing herself, she begins to think that maybe death doesn't sound so bad after all. In an attempt to save what's left of their shattered family, Daisy's parents seek out professional help from Ava Blume, a psychologist whose tragic past is far more complicated than even Daisy's. With Ava's help, Daisy manages to get her life back on track. But when heartbreak comes knocking a third time, Daisy must make a difficult choice-succumb to the depression and anxiety that has crept back into her life or take a chance and give life and love another shot.
