Hollow's Edge used to be a quiet place. A private and idyllic neighborhood where neighbors dropped in on neighbors. But then came the murder of Brandon and Fiona Truett. A year and a half later, Hollow's Edge is simmering. The residents are trapped, unable to sell their homes, confronted daily by the empty Truett house, and suffocated by their trial testimonies that implicated one of their own. Ruby Fletcher. And now, Ruby's back. With her conviction overturned, Ruby waltzes right back to Hollow's Edge, and into the home she once shared with Harper Nash. Harper, five years older, has always treated Ruby like a wayward younger sister. But now she's terrified. What possible good could come of Ruby returning to the scene of the crime?
