The mind is a dangerous place . . . especially when you can't trust your own.

Dr. Hadley Dawson's revolutionary theory-that even the darkest minds can be healed-has made her a rising star in criminal psychology. But when a string of unexplained deaths leads back to a former patient, her life's work suddenly stands in question.

When the poster boy for her rehabilitation program is accused of murder, Hadley's conviction begins to crack. Has she been blind to the darkness lurking within those she sought to save?

Detective Josiah Brennan, her late best friend's husband and once her staunchest ally, now questions Hadley's judgment. Their friendship frays as the evidence mounts, forcing Hadley to confront an unsettling truth: her quest to reform criminals may have unleashed a killer.

With her reputation in tatters and her theories in doubt, Hadley races to uncover the truth. But each revelation only deepens the mystery. Is someone orchestrating an elaborate plot to destroy her career? Or is the threat more sinister-aimed at claiming her very life?

In a heart-pounding race against time, Hadley must outwit a cunning adversary before she becomes the next victim. But in a world where minds can be manipulated, who can she really trust?
