Eleven-year-old Verbena Polter gets through a difficult summer of turbulent emotions and the revelation of a disturbing family secret with an odd new friend who believes she is the ghost of a girl who drowned many years before.

All her life Aurora has heard stories about how wonderful and lucky Heidi is, and soon this paragon (now grown up and expecting a baby) will be visiting; but before she arrives part of their house is damaged in a fire, and worse, Aurora's beloved dog disappears--and while her parents have always believed in "soof" (Heidi's mom's word for love), Aurora, who has never really fit in with children her own age, will just have to find her own soof.

After spending her life with her mentally disabled mother and agoraphobic neighbor, twelve-year-old Heidi sets out from Reno, Nevada, to New York to find out who she is.
