Perfect for you if...

  • You love detective thrillers with a personal stakes angle, where the investigator becomes entangled in their own case.
  • You're drawn to atmospheric mysteries set in isolated locations where danger feels genuinely claustrophobic.
  • You've read the previous Riley Quinn books and want to see where her arc leads after this catastrophic event.

Maybe not for you if...

  • You prefer standalone mysteries and don't want to commit to a six-book series to understand the full picture.
  • You're squeamish about dark content involving missing children and arson; this book leans into both heavily.
  • You dislike protagonists with trauma histories that resurface; Riley's past is central to unravelling the present mystery.

About this book

In a wooded area, someone or something is watching closely. Teenage girls disappear during a game of hide-and-seek, with only one returning to the campfire after being blindfolded and taken away. Detective Riley Quinn, who has spent much of her life fighting evil, is found unconscious by firefighters and discovers her home has been set on fire. As her memory returns in fragments, she identifies a shadowy figure connected to that night, uncovering a truth darker than expected. With multiple arson cases mounting and a cold case intersecting with ongoing investigations, the mysteries take unexpected turns, revealing a monstrous reality. Disappearances, deaths, and bombs in preparation converge as Quinn works to bring down the perpetrator through a final trap of justice.
