Several adult non-fiction books are being released for a younger audience
Lately I’ve been noticing that more and more authors seem to be adapting their adult nonfiction books for younger readers (typically for the middle grade set, ages 8-12). The young readers editions are shorter and often contain more illustrations, photos, graphs, and charts than their adult counterparts, distilling the story and information down into what would be in the movie versions of these books. Here are some of the young readers’ editions I’ve run across.

I would also throw in adult fiction books such as The Martian. Not only has the language been re-done to be school appropriate, activities have been added.
