Perfect for you if...

  • You love psychological thrillers where the past catches up with seemingly respectable people and they have to face what they've done.
  • You're drawn to stories about women keeping dangerous secrets and the psychological toll of maintaining a lie for decades.
  • You enjoy multi-timeline narratives that reveal how one moment of youthful recklessness can reshape an entire life.

Maybe not for you if...

  • You prefer fast-paced thrillers with constant action; this one builds tension through secrets and psychological unravelling rather than plot twists.
  • You want clear-cut heroes and villains; Emma is morally complicated and sympathetic despite being complicit in something terrible.
  • You're looking for a cosy mystery or light read; this explores dark themes including the consequences of a crime committed by children.

About this book

Janie Klassyn was fourteen when she and her friends made a blood pact, unknowingly setting in motion a horrifying crime that devastated her small prairie town. Twenty years later, Emma Grant—now a school counselor in California—works to keep her past hidden. When a threatening note appears on her car promising to expose her secret, maintaining the deception becomes impossible. Her teenage stepdaughter grows suspicious of what Emma is concealing. As her true-crime author husband investigates a decades-old murder case for his next book and a suspicious accident involving someone who has been following her occurs, the stable life Emma has constructed begins to fall apart. Facing exposure, she takes desperate measures to protect what she has built.
