Mara Voss is a celebrated true crime author who has made a career out of dissecting the minds of killers from the clinical safety of her keyboard. But when her editor pushes her to investigate the "Lakeshore disappearances"—a string of cold cases involving women who vanished without a trace from the isolated town of Aldermoor—Mara leaves the city behind to imbed herself in the community.
There, she meets Céleste Arnaud, a enigmatic local florist whose quiet stillness and deep roots in the town both compel and unsettle her. As winter closes in and the town's guarded secrets begin to fracture, an intense, slow-burn relationship develops between the two women. Surrounded by the dense woods and shifting fog of the lakeside, Mara finds herself caught in a psychological labyrinth where the boundaries between investigator and subject blur, forcing her to confront a devastating question: what are we willing to ignore in the people we love?
