Into every generation a Shadow Guardian is born. They are here to stop the dark forces from spreading their evil and the swell of their number on earth. They are human by nature without any supernatural attributes; therefore, an angel is assigned to protect each one of them. When the Shadow Guardian dies, their first descendant, "the chosen one," is called into action, but they must be at least eighteen to take on the task. Jade is the chosen one, the descendant of the Shadow Guardian and she is clueless of her heritage and the life-changing secret her mother took to the grave. A guardian angel is sent to protect Jade to make sure she makes it to her eighteenth birthday. He has been watching over her, waiting for the right moment to reveal his identity, but he has done more than protect her, he has secretly fallen for her. It is up to her to take on the role of the Shadow Guardian and follow an unwanted legacy -but her vulnerable and innocent heart may hinder her from fulfilling her destiny and possibly end the bloodline of the Shadow Guardian.
