Fun book about packhorse book delivery in coal country in the 1930s. Because I'm a snot, I won't call the riders "librarians." The one person who seemed to have any actual library training, Sophia, had to stay back in the library HQ because she was Black. It's billed as a romance, and the book contains multiple heterosexual unions. I think at least one character might have been a little queer. One possible lesbian and one likely asexual. Despite the culminating romances, the book is more about women coming together to fight sexism and an asshole coal tycoon. I am always up for a book about defeating an asshole coal tycoon!
