Perfect for you if...

  • You love psychological thrillers where nothing is quite what it seems and the protagonist's motivations become increasingly complicated.
  • You're drawn to stories about wealth, power, and corruption where the rich can operate without consequence.
  • You appreciate tight plotting with genuine twists that recontextualise what you thought you knew about the central mystery.

Maybe not for you if...

  • You prefer slow-burn character studies over plot-driven narratives with multiple reversals.
  • You need a protagonist you can wholly root for without moral ambiguity clouding their actions.
  • You're looking for a standalone mystery rather than the kind of thriller that hinges on shocking revelations about who characters really are.

About this book

Isla Thorne was orphaned young and spent her formative years in a group home, where she met her best friend Eden Galloway. At sixteen, the two planned to run away to Los Angeles, but Eden never arrived. Ten years later, Isla remains determined to find Eden. She begins her search at the Corrigan mansion in Virginia, the last place Eden visited before disappearing. Posing as an aspiring journalist, Isla embeds herself in the wealthy family's home to uncover what happened. As Isla investigates, she learns that Eden may not be who she believed. She questions whether Eden was a victim or if she orchestrated her own disappearance. Seeking answers while protecting her true identity, Isla forms an alliance with one of the Corrigan sons. However, as she uncovers the family's secrets, she discovers she has become a target of a powerful bloodline driven by lethal loyalties. This thriller examines themes of revenge, morality, corruption, and wealth.
