Twenty-something twins Jill and Joanna Mason aren't impressed with adult life so far. Bored with her career, Jill dreams of pursuing adventure but fears romantic entanglements. Joanna has no problem dating; however, a series of unhealthy relationships have derailed her fiction-writing dreams. A vacation to England is just what they need. But the twins get more than they bargained for when they are mysteriously transported to Medieval Sherwood Forest. Captured by Guy of Gisbourne, Joanna must investigate why young women in his castle are dying. To save her sister, Jill enlists the aid of Robin Hood who she finds isn't exactly a criminal mastermind. In this light-hearted adventure, the sisters will have to solve a murder, tutor an incompetent outlaw, and navigate matters of the heart if they're going to find a way back to the twenty-first century.
