Overdue for a Cowboy by Jennie Marts

Sweet librarian, Maisie Graham, has a passion for books as vast as the Colorado skies. Armed with her trusty bookmobile, she journeys to rural farmland bringing the magic of books to kids who can’t make it to town. But there’s one story she’s never dared to dream—the tale of her and the rugged cowboy, Dodge Lassiter, the man she’s harbored a crush on since high school. Hidden behind her glasses, she sees herself as a plain Jane in a world full of glamorous and much more adventurous heroines.
Dodge Lassiter has enough on his plate trying to run the family ranch where he and his two older brothers were left when they were kids. A fear of abandonment runs deep in his veins, making him hesitant to open his heart to romance, even if he is drawn to Maisie’s kindness and intellect. He thinks she’s amazing and deserves someone better than a nerdy cowboy who spends most nights hanging out with a good book and his dog.
But fate has a way of stepping in where love is concerned, and suddenly Maisie and Dodge find themselves the only two members of a secret book club, the shared owners of a rescued llama named Phyllis, and spending hours together bumping along dusty mountain roads in the bookmobile. As Maisie battles her self-doubt and Dodge wrestles with the ghosts of his past, can they find the courage to write a new chapter together?
