"With his in-depth knowledge of science and medicine, Don Donaldson is one of very few authors who can write with convincing authority."

Tess Gerritsen, author of the Rizzoli and Isles series.

Don Donaldson pens a gripping, psychological thriller. . .

Nothing in this mysterious asylum is what it seems.

She's being destroyed by an unknown opponent-one memory at a time.

Dr. Marti Segerson's appointment to the staff of the isolated and rural Tennessee Gibson State Mental Hospital was no accident. Years ago, Marti watched a madman, serial killer Vernon Odessa, murder her sister. Marti never forgot the horror. Never gave up on revenge.

Gibson State may finally hold the key to justice. Odessa is incarcerated within the gloomy, medieval-walled asylum. He's within her reach, but her carefully planned retribution may get her killed. Only days after her arrival, her memory is suddenly riddled with holes. Someone's carefully orchestrated mind games are blurring the line between illusion and reality.

Soon, she's not certain whether she'll get justice for her sister or become the next victim.
