Before I saw the sub, I thought this would be cool if it were done well.
My reasons are:
My dyslexic, ADHD niece who loves to read, this could help her enjoy a classic she wouldn't consider trying, and give her a sense of accomplishment. Instead of being restricted to simpler books.
Students with a different first language. My friends used cheats, coles notes and audiobooks to try to keep up in school. Books written like this would do more to help build literacy.
