I see educators asking all the time for lists of books on all topics and genres. I will create some here, including both recent publications and relevant (hopefully still in print) older titles. If you have any suggestions that would qualify, please add them in the comments.
Medieval Fiction List – useful for middle grade classes studying Medieval History and need a supporting (optional) fictional text. Includes books from Western and Eastern cultures. Also books set in fantasy worlds, but that offer lifestyles similar to a medieval landscape.
