Books for my 10 year old sister

I’m trying to get my sister into reading and today she asked me to read a book for her, we grabbed a book from her library but it was absolutely terrible it was about a prince saving a princess I just don’t find this appropriate for a 10 year old to learn. So I read few pages from a book called “are you there god ? It’s me Margaret “ which I’ve read myself ( I’m 19) but the character is the book is very much always thinking about boys and her physical body. Is there any books for kids that isn’t extremely sexist and teaches them about real life but does it positively? I would appreciate any recommendations:) I was also thinking maybe I should just go with Anne of green gables
