From the New York Times bestselling author of The Flight Attendant comes a spine-tingling novel of lies, loss and buried desire—the mesmerizing story of a wife and mother who vanishes from her bed late one night. Gorgeous, blond, successful, living in a beautiful Victorian home in a Vermont village, Annalee Ahlberg has another side: at night she sleepwalks, and her affliction manifests in ways both devastating and bizarre. A search party combs the woods, but there is little trace of Annalee and her family fears the worst. Her daughter Lianna leaves college to care for her father and younger sister. She finds herself uncontrollably drawn to Gavin Rikert, the hazel-eyed detective investigating the case, and the two become involved. But Gavin seems to know more about Lianna's mother than he should. As Lianna sifts through the life Annalee has left behind, she wonders if the man sleeping next to her could hold the key to her mother's mysterious disappearance.
