Perfect for you if...

  • You enjoy thrillers that shift beneath your feet, where the mystery keeps expanding beyond what you thought it was about.
  • You've watched The X-Files and want that same sense of conspiracy and unexplained phenomena wrapped in a gripping page-turner.
  • You like protagonists with baggage who have to solve an impossible case whilst their personal world falls apart around them.

Maybe not for you if...

  • You prefer closed-room mysteries where all the clues are on the table and you can solve it yourself.
  • You want straightforward crime procedurals without supernatural or science-fiction elements creeping in.
  • You need neat resolutions. This book leans into ambiguity and the genuinely inexplicable.

About this book

Ex-cop Jack Whalen is approached by a childhood friend, a lawyer, to help investigate the brutal murder of a scientist's family. The scientist has vanished without a trace. Jack's personal troubles compound the case. He left the L.A.P.D. due to unresolved issues from his past, and now his wife has disappeared during a business trip to Seattle—she never arrived at her hotel and is not responding to calls. When a missing girl from Oregon is discovered miles away, Jack realizes she is neither an innocent victim nor helpless. As Jack pursues these interconnected disappearances, he uncovers a series of strange and troubling events that lead him into dark territory, where the secrets he discovers are far stranger than he could have anticipated.
