Fern and Paul seek refuge in a new home after a devastating loss, only for Fern to become consumed by the secrets of the previous occupant. Fern, grieving the loss of her twin sister and pregnant with her first child, moves into an old house with her husband Paul, hoping for a fresh start. However, her newfound peace is shattered by disturbing nightmares about the house's former resident, a woman with whom she shared a pregnancy bond. As Fern's obsession grows, Paul fears a relapse into the same destructive patterns she exhibited after her sister's death, while the neighbors remain eerily silent about the woman who seemingly vanished. Fern must unravel the fatal secret hidden within the house before her family is endangered.

The premise sets up a tense domestic thriller, focusing on a protagonist grappling with grief and a potentially supernatural or psychologically driven obsession within the confines of a new home. The narrative appears designed to build suspense through Fern's deteriorating mental state and the mystery of the previous occupant, suggesting a pacing that accelerates as Fern uncovers more dangerous truths. The comparison to authors like Louise Candlish and Claire Douglas indicates a market for psychological suspense with a strong focus on character and atmosphere. This suggests a reading experience that is likely to be immersive and unsettling, with a climax driven by the revelation of a dark secret.
