Yes, still on juvenile books, as far as I know.
A Year Down Yonder by Richard Peck. Haven't read it, but I heard it's a good story.
I have to mention The Watsons go to Birmingham, 1963. It's very funny, but touches on serious issues like racism, and the church bombing that killed several little girls. If you have children who are in 6th or 7th grade, they'd probably enjoy this book.
