Rushing to work in New York in the winter of 2016, Melanie Swift is hit by a truck on the icy city street. Drifting in and out of consciousness, she "wakes up" on a freezing bench in Boston, shocked to find that, not only is she in a different city, but that it's the year 1886. There, she meets a young doctor who falls in love with her and takes her to live in his home with him and his sisters. Confused and homesick, Melanie tries to adjust, but she can't give up hope that she'll somehow be reunited with the man she loves in own time. But what if she's forced to live out her life in the past? Should she give in and learn to love the man who so clearly loves her, or continue to pine for a man who won't even be born for another hundred years? And, most importantly, how can she be sure that her actions in the past won't change the future in some terrible way?
