Mia Jarvis is one of the Daughters of Sable, girls possessing unique gifts enabling them to perform extraordinary tasks. However, as a child, Mia’s father always emphasized to her that the most important ability… was dependability. For almost a decade, her commitment to dependability served her well. By the time she hit twenty-four, she had a good job, a reliable car, and great friends. What more could a girl ask for? But once she takes her friend Erin up on an offer she can’t refuse, Mia’s entire world turns on end, and she finds out that, while she may be in love with The World’s Greatest Guy, she is also at risk of being destroyed by an evil nun… who has enlisted one of her friends for help!
