Here are just a few of her books, some of them among her most popular, as well as Newberry Award winners:
Many of her books are already on reading lists in schools, but several including Bridge to Terabithia and Jacob I Have Loved have been banned or challenged due to content. Regardless of what "they" may say about why her books shouldn't be on every reading list there is for middle and high school, Katherine Paterson's books touch deep to the core of the way a girl thinks and feels during intense situations. I also love how she often blends historical facts into her novels, to give you a sense of a time we've never lived in, and the struggles a teen girl would go through in that period.
I highly recommend giving Katherine Paterson a try, if you haven't already. She is definitely one whose work should not be missed.
