Linda Morgan investigates the people who claim to heal wounded minds but exploit them instead. Her latest case appears at first to be another complaint against an unlicensed therapist: Jeff Danials, a charming self-styled shaman accused of crossing every boundary with the women who trusted him.

But as Linda follows the trail of missing victims, strange gifts, surveillance, intimidation, and violence, the case turns into a personal nightmare. Jeff has secrets, and so do the people around him. The deeper Linda digs, the closer she comes to a terrifying truth: the man she is investigating may not merely be dangerous. He may be hunting anyone who can expose him.

Set against the tense urban backdrop of Minnesota, The Therapist's Darkest Secret is a psychological thriller about obsession, manipulation, false healing, and one investigator's fight to survive the darkness she uncovers.
