De Smet, South Dakota—1890 
Young women growing up in De Smet live by two rules: don’t go out in a snowstorm and don’t give your heart to Cap Garland. Young Mariah Patterson only managed to obey one. Orphaned and having devoted her youth to scrapping out a life with her brother Charles, Mariah finds herself with no option but to marry the devoted—but dull—Merrill Gowan. Throwing caution to the wind, she seizes an opportunity to lay her feelings at Cap’s feet, even though she knows Cap sees the world through the torch he carries for Laura Ingalls. Mariah is certain her love for Cap will be strong enough to break both bonds, and she’s willing to risk everything to prove it. 
 
De Smet, South Dakota—1974  
Trixie Gowan is the fourth generation of living Gowan women residing in the sprawling farmhouse on the outskirts of De Smet. Well, former resident. She’s recently acquired her own bachelor girl apartment in Minneapolis, where she works writing ads for a neighborhood paper. She might live and work in the city, but her co-workers still call her Prairie Girl. Thus the inspiration for her comic strip—"Lost Laura"—in which a bespectacled girl in a calico dress tries to make her way in the city. The name is a quiet rebellion having grown up in a household where she’d been forbidden to mention the name, Laura. But when her great-grandmother Mariah’s declining health brings Trixie home for a visit, two things might just keep her there: the bedside manner of Dr. Campbell Carter and the family secret that seems to be spilling from GG’s lips one conversation at a time.
