On a blistering summer day in 1968, nine-year-old Tommy vanishes without a trace from Coram House, an orphanage on the shores of Lake Champlain. Some say a nun drowned him, others say he ran away. Or maybe he never existed. 50 years later, his disappearance is still unsolved. Struggling true crime writer Alex Kelley needs a fresh start. When she’s asked to ghostwrite a book about the orphanage --- and the abuses that occurred there --- she packs up her belongings and moves to wintry Burlington, Vermont. As Alex tries to untangle the conflicting stories surrounding Tommy’s disappearance, her investigation takes a chilling turn when she discovers a woman’s body in the lake. As the body count rises, Alex must prove that the key to finding the killer lies in Tommy’s murder, or risk becoming the next victim.
