A kidnapped psychologist. A murderous warden. There's more to this prison than meets the eye...

Dr. Raine Walsh has a right to be paranoid. The expert psychologist has spent far too much time in the minds of the criminally disturbed, but that's no reason for her to be drugged and thrown into prison. Raine can't remember the crime that got her locked up, and she wonders if her growing paranoia has destroyed her sanity...

Raine is determined to solve the mystery of her twisted incarceration, but finding allies is a dangerous game. Some of her fellow prisoners are far from innocent, and a guard confides that he's also been kidnapped and forced to play a role. The problem is that the warden controls the compound with an iron grip. Her only chance of escape could put her and the other inmates in grave danger...

The Altruism Effect is the first book in a series of psychological thrillers. If you like gripping suspense, realistic characters, and mind-bending plot twists, then you'll love Kristin Helling's kidnapping thriller.
