Perfect for you if...

  • You loved The Marsh King's Daughter and want more of Dionne's unsettling family mysteries set in isolated Michigan.
  • You're drawn to unreliable narrators with fractured memories where the truth keeps shifting beneath your feet.
  • You enjoy psychological suspense that hinges on sister relationships and questions what nature versus nurture actually means.

Maybe not for you if...

  • You prefer fast-paced plots with clear answers. This one unfolds slowly through gaps in memory and competing versions of the past.
  • You want an uplifting read. The novel dwells in trauma, guilt, and the poisonous bonds within families.
  • You need graphic violence on the page. The murders happened years ago, and the tension comes from not knowing what really occurred.

About this book

Rachel Cunningham has spent fifteen years in a psychiatric facility, believing herself responsible for her parents' deaths when she accidentally shot and killed her mother as a child. But when she discovers new details about their murders, she questions everything she remembers. Rachel returns to her family's log cabin in Michigan's Upper Peninsula to uncover the truth about what happened the day her parents died. As she investigates, she learns that home harbored unspeakable evil, and that her relationship with her sister may be far more dangerous than she realized. This novel of psychological suspense explores two generations of sisters as they confront questions of nature and nurture, guilt and betrayal, love and evil—and whether Rachel's past is truly what she has always believed it to be.
