Perfect for you if...

  • You love detective series with a central mystery that keeps shifting beneath your feet, like Lisa Regan or Kendra Elliot's work.
  • You want a thriller that hinges on procedural investigative work rather than relying solely on action set pieces.
  • You appreciate protagonists who are both capable professionals and complex people with their own lives outside the case.

Maybe not for you if...

  • You prefer standalone novels over series commitments, as this is book four in the Alyssa Wyatt sequence.
  • You're squeamish about graphic depictions of violence, as this one contains a bloodbath and disturbing cult imagery.
  • You want your thrillers fast-paced and lean; this 352-page novel takes time building investigation details.

About this book

Three best friends—Skye, Elena, and London—gather for their usual Thursday night at Skye's house in New Mexico, enjoying food, wine, and time with Skye's children, Carter and Abigail. The evening is interrupted when intruders arrive. After hearing horrific screams, London hides the children and goes to investigate, then vanishes. When Carter alerts authorities, Detective Alyssa Wyatt is called to the scene of a brutal crime with no clear motive, no evidence, and no sign of London. As Alyssa and her team investigate, they struggle to find answers. The case becomes more urgent when they uncover a connection between the murders and a sinister local cult. Alyssa must work quickly to locate London before she becomes another victim. This is the fourth book in the Detective Alyssa Wyatt series.
