Melissa is learning the world isn't what she thought it was. When she meets a group of Liberators who oppose the Cyborg Eradication Project, she agrees to join an expedition set on freeing a group of cyborgs. Thunder wants to free his cyborg brothers too. He takes Melissa prisoner, only to find that she stirs strange new feelings in him - primal, powerful urges he has neither the ability nor the desire to control. Melissa can't fight her attraction to the massive soldier-cyborg holding her captive. But soon they're surrounded by Purity Force, and their chances of survival are slim. Can she and Thunder find a way to escape? If they do, will humans and cyborgs tear them apart?
