She thought she had been kidnapped. The truth was far worse.

Sarah Hudson wakes in a facility with no idea how she got there and memories of her family already slipping away. But one certainty remains: She doesn’t belong at Bright Horizons.

Detective Harris is chasing a cold case that leads him to the facility’s door… and to Anna Cline, the director with a secret and a conscience cracking under pressure. But it’s Michael Greene who poses the real threat: a once-brilliant researcher now coming undone, and willing to kill to keep the truth buried.

What exactly is Bright Horizons—and what’s happening to Sarah Hudson inside its walls?

As Sarah fights to reclaim her memories, Harris and Anna must work together to stop Michael before he silences them all.

Fans of The Silent Patient and Gone Girl will devour this haunting psychological suspense that will keep you guessing until the final page.
