Maggie Brock has everything under control. Even her divorce, though painful at the time, only registers as a minor blip in her carefully constructed universe. Her life in Prairie Oaks has once again returned to a smooth, predictable pace...until an angel shows up in her bedroom. The angel is just as bewildered as Maggie about why he's been sent to her, but their unsuccessful efforts to gain understanding of the mystery fade to the background as their relationship grows. Soon, Maggie's biggest problem becomes the angel himself, as her feelings for him develop into something less than saintly. While Maggie struggles to keep her desires pure, a nefarious being lurks in the shadows of Prairie Oaks, watching and waiting for the opportunity to fulfill his ambiguous purpose. Preying on her conflicted emotions, the demon manipulates her at every opportunity, but the one to deliver Maggie directly into his hands is the last person she'd expect.
