A fatal mistake stripped Zach Roderick of the powers that define him, leaving him a tormented shadow of the warrior he once was. Now, his teammate's life depends on Zach resurrecting the fire that once burned within him. As he undertakes a battle he has no way to win, he is derailed by a tempestuous beauty that awakens in him the dark desires that destroyed him once before. The scars etched on Rhiannon Diaz's soul are so deep that she will never again be free. The once-powerful guardian is facing her last and greatest battle, and failure means a return to a sexual enslavement that is far worse than death. Her intense and passionate need for the powerful warrior who has vowed to protect her threatens the very foundation of her survival, but his refusal to abandon her drags them both into a world where wild, untamed passion rages, and surrender is their only chance.
