Some secrets live right next door.
June Adler has built a perfectly structured life in the affluent suburbs of Briar Lake. As a real estate appraiser, she knows how to look past fresh paint to spot structural flaws. But she completely missed the one living under her own roof.
When her flawless babysitter, Lily, vanishes without a trace, June searches the girl's empty room and finds a hollowed-out book containing ten fake IDs and a twenty-year-old photograph. The photo was taken on the exact night June's college best friend, Cassie, mysteriously disappeared.
The horrifying truth quickly comes into focus: Lily is actually Rose, Cassie's daughter.
Forced to re-evaluate everything she thought she knew, June pulls at the threads of the past and uncovers a chilling web of coercive control, domestic manipulation, and stalking. She discovers that Cassie has spent fifteen years running from a relentless predator who went to unimaginable lengths to isolate her-including intercepting thirty-seven letters sent to June's mailbox.
The most terrifying part? The man responsible isn't a shadowy stranger. He's a beloved father, a PTA volunteer, and a trusted neighbor living just two blocks away.
