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. Fifty years later, the opportunity to investigate his disappearance and the orphanage's sinister history is just the break that struggling true crime writer Alex Kelley needs.

Arriving in Vermont for research, Alex grows obsessed with Tommy's disappearance, then her investigation takes a harrowing turn with the discovery of a woman's body in the lake. Alex is convinced this new death is somehow connected to Coram House's dark past, even if Officer Russell Parker thinks she's just desperate for a story. As the body count rises, Alex must prove that the key to finding the killer lies in a decades-old murder--or else she risks becoming the next victim herself.
