Perfect for you if...

  • You want a psychological thriller with a genuinely disturbing premise and a protagonist you'll hate yourself for understanding.
  • You're drawn to unreliable narrators and moral ambiguity, especially when the stakes involve life and death decisions.
  • You like crime stories that flip the script: instead of catching a killer, the protagonist is trying to stay invisible.

Maybe not for you if...

  • You're sensitive to content about suicide and self-harm, as the book explores these themes in uncomfortable detail.
  • You prefer protagonists with clear motives and understandable backstories; Laura's darkness isn't easily explained away.
  • You want feel-good stories or straightforward procedurals; this book lives in moral grey zones that won't resolve neatly.

About this book

An ITW Thriller Award finalist. Laura works at End of the Line, a crisis helpline where callers seek hope and reassurance. Unlike her colleagues, Laura actively discourages callers from living. She has survived illness and a difficult marriage and is now in her late thirties, angry and unsettled. She finds satisfaction in speaking with people in worse circumstances than herself. When Ryan's pregnant wife dies by suicide alongside a stranger, he becomes determined to uncover the truth about the man involved. His investigation brings him closer to Laura's dark secret, though he remains unaware of her involvement and the lengths she will take to protect herself. This revised edition includes editorial revisions and an exclusive epilogue that enhances the reading experience while keeping the main narrative unchanged from earlier editions.
