What are good partner books for a kid in 6th grade that is on a 8th grade level?

Wow! Your child really likes dramatic situations for only a sixth grader. Well I am in grade 9 but am on a grade 9 level. So I would try the Wind in the Willows. Even though its not dramatic it would be challenging because your daughter is only in grade six and shouldn't be talking about pregnancy or boyfriends. I think the wind in the willows would be a great book! Good luck to your daughter and partner!
