Perfect for you if...

  • You love psychological thrillers that mess with your head and keep you guessing about what's real until the final pages.
  • You're drawn to stories about complicated family bonds and the secrets we keep to protect the people we love.
  • You appreciate unreliable narrators and don't mind being completely wrong about what you think is happening.

Maybe not for you if...

  • You need a protagonist you can root for unambiguously, because both sisters have complicated motivations and murky pasts.
  • You prefer plot-driven stories where the mechanics of the mystery are airtight, because this prioritises character psychology over puzzle logic.
  • You're looking for a hopeful or redemptive ending, as this book leans into the damage trauma creates.

About this book

Foster sisters Krystal and Nichole have always depended on each other to escape their troubled past. When Nichole is committed to a psychiatric hospital after attempting to kill her husband, Krystal abandons her own life to defend her sister. Despite a difficult upbringing, both sisters have built stable lives—Krystal as a respected lawyer and Nichole as a happily married woman to an architect. This changes when Nichole begins insisting her husband is an imposter. Driven by loyalty, Krystal investigates her sister's claims, but her questions lead back to a dark shared history: a terrible tragedy and a carefully kept secret that bound the sisters together. As Krystal uncovers the truth, both sisters must confront the past they left behind before it destroys the lives they have built.
