Perfect for you if...

  • You love procedural crime fiction where the detective's personal chaos mirrors the case complexity, like Mindhunter or Criminal Minds.
  • You're invested in character-driven mysteries where the partnership between agents matters as much as the investigation itself.
  • You want detailed forensic work and crime scene analysis that feels authentic, not Hollywood shortcuts.

Maybe not for you if...

  • You prefer standalone thrillers over series commitments. This is book three in a sequence and builds on previous cases.
  • You're sensitive to graphic violence involving children. The killer's victims include minors and the descriptions are unflinching.
  • You want lighter procedurals with wit and banter. This is dark, bleak, and psychologically heavy throughout.

About this book

A contractor discovers a crime scene at an abandoned construction site, leading the county sheriff to suspect an isolated incident. When a second crime scene appears in a different county, it becomes clear that a serial killer is targeting women and children. As media coverage intensifies and news of the active killer spreads, ASAC Blackwood sends Special Agents Sadie Gray and Brad Tulle to investigate. Sadie, recovering from trauma from her previous case, claims readiness for the hunt despite personal struggles and relationship complications. She relies on Brad at work and her friend Aria at home as the investigation unfolds. The killer operates across empty houses—from framed construction to nearly completed builds—leaving bodies and death in each location. As clues accumulate without clear direction and frustration mounts, the situation deteriorates rapidly. The killer adapts faster than Sadie and Brad can respond, potentially unleashing a spree of violence unprecedented in California's capital city. The investigation becomes deeply personal for both agents as they work to identify and stop the killer before more victims are claimed.
