When her dark past threatens to resurface, she decides to take precautions to protect herself by enrolling in self-defense classes at her gym. Her instructor, Ryker Campbell, is the tattooed womanizer everyone warns about. Kaiya attempts to resist Ryker's advances, but the more time they spend training together, the harder it is for Kaiya to resist him. Ryker's view on relationships is simple: strictly sex, nothing more. Haunted by demons from his past, he never allows himself to become attached to any woman. No attachment means no weakness, no vulnerability, no pain. He doesn't realize that his whole world is about to be turned upside down when Kaiya enters his self-defense class. Determined to have her, at least for one night, Ryker sets a plan into motion that will change both of their lives forever. Will love be able to heal their scars, or are they too deep to overcome? less

Even though Kaleb is out of Kaiya's life, the scars he left behind remain a constant reminder of the pain he subjected her to for most of her life. Still tormented by those old demons, and plagued by the events of that traumatic night, Kaiya has more to deal with as she moves forward with Ryker. Ryker's past continues to haunt him when something unexpected flips his and Kaiya's lives upside down. Neither are prepared for what's to come... moreEven though Kaleb is out of Kaiya's life, the scars he left behind remain a constant reminder of the pain he subjected her to for most of her life.
