Francine "Frankie" Weston is an independent woman. She moved to Idaho to homestead with her older brother at the tender age of seventeen, pretending to be a man. Now, at twenty, she's ready to marry, but she doesn't want to admit she's deceived everyone, so she sends for a mail order groom—one who's willing to take her last name. She doesn't think it's possible, but she's willing to wait for just the right man to make her happy.
Wallace Miller, a former member of the demon horde, feels like his life is going nowhere. His reputation as a troublemaker has followed him into adulthood, and he can't seem to catch a break. When his older sister, Elizabeth, shows him a letter from a woman wanting a man to marry, he's shocked before he sees the potential of the situation. Meeting his pants-wearing independent bride comes as a bit of a shock. Will the two of them be able to come to a compromise about how a lady should act? Or will they be destined to be partners in life, but never partners in love?
