"New York Times" bestselling author Margaret Weis teams up with her daughter for a paranormal romance series featuring good but flawed Guardian Angels striving to protect their mortal charges, never expecting to fall in love. Derek is a fallen angel, formerly of the Knights Templar. Disillusioned with God and his grand plan, he chooses to remain forever in Limbo, fighting against the Dark Angels, rather than enter into Heaven. But then news of impending war between the forces of good and evil sends Derek to save mankind. Rachel Duncan is a focused business woman - so focused that she has no idea that her new client is one of the Dark Angels, determined to use Rachel in a master plan to send the world into chaos. Caught up in his charming web, Rachel doesn't realize how deeply she's involved until it's too late. Now she and Derek are in a race against time, as Rachel gets drawn farther into the Dark Angel's plans, and Derek confronts obstacles to her rescue at every step. Will they be able to overcome the forces of evil and their own misgivings to save the world...and each other?
