When a young woman is found murdered by the roadside, Lily's connection to the case runs deeper than anyone suspects. Haunted by a traumatic past and pursued by relentless investigators-including her own family members-Lily is drawn into a web of secrets and deceit. As old wounds reopen and hidden truths surface, she must navigate suspicion, danger, and her own fractured memories before the darkness claims her too. Trust is a luxury, and survival means facing both the dangers outside-and inside-her own mind.

For brilliant forensic anthropologist Dr Lilly Prior, the dead are preferable company. Her sterile lab is a sanctuary where the only language spoken is the quiet, logical truth of bone. But when the aggressively charming FBI Agent Jake Booth summons her to a bizarre crime scene-a skeleton posed at a macabre mannequin dinner party-her carefully controlled world is shattered. This is no ordinary killer. He calls himself The Watcher, an artist who leaves behind pristine white feathers and cryptic symbols carved directly into his victims. He's a ghost who can walk through secured perimeters, and his terrifying, personal messages make one thing clear: this elaborate, deadly performance is all for Lilly. Forced into an uneasy alliance with the infuriatingly handsome Agent Booth, Lilly must decipher The Watcher's horrifying riddles while navigating a threat she can't analyse: her own undeniable connection to the one man who might breach her defences for good. As the killer's obsession escalates, Lilly becomes the central piece in a terrifying game where losing is not an option.
