Katie Stuckey and Jonas Weaver are both romantics. Seventeen-year-old Katie is starry-eyed, in love with the idea of being in love, and does not want to wait to marry Jonas until she is eighteen, despite her parents' insistence. So much can happen in a year. Twenty-year-old Jonas is taken in by the romance of soldiering, especially in defense of anti-slavery, even though he knows war is at odds with the teachings of the church. When his married brother's name comes up in the draft list, he volunteers to take his brother's place. But can the commitment Katie and Jonas have made to each other survive the separation?
