Set on Kentucky's Blood River, a Sheriff's Deputy investigates the death of her ex-fiance, whose brutal occultist murder strongly resembles a similar murder decades ago, for readers of Tana French, Gillian Flynn, Megan Abbott, and fans of True Detective

Deputy Sheriff Alicia Moore is thrust into the center of a chilling murder investigation when she discovers a victim identifiable only by his hauntingly familiar tattoo-her name inked onto the knuckles of her ex-fiancé, Jake.

Years earlier, Alicia's father, the then-Sheriff, had arrested a teenage occultist for a nearly identical murder, believed to be driven by the suspect's worship of demonic entities. Now, with Jake's murder mirroring that past crime, doubts arise about whether the true culprit was ever caught. The mystery deepens with the arrival of Lucas Masterson, a Criminology PhD student studying the confluence between religious trauma and occult crime, who is eager to lend his expertise to the investigation. As Lucas delves into the case, his profound knowledge of the town's grim history and his outsider perspective strain the local social fabric, while Alicia grapples with her suspicion towards his unsettling familiarity with the crimes. Caught between her strained relationship with her father, the community's watchful eyes on a female deputy, and her own harrowing ties to the case, Alicia must navigate a maze of potential occultists, convicts, corrupt officials, and clergy to prevent a gruesome history from repeating itself once again.

For what lies at the heart of Blood River - is it an ancient malicious force seeking to harm the townfolk, or is there a deeper prejudice in a town that continues to punish women in a way that it does not punish the men?
