I read an article a while ago about some of the best chapter books for kids. It was actually a list for girls, but it could go for boys and girls. The first set of chapter books on the list was the Rainbow Magic books. I had never heard of them. We downloaded a few audio books and the narrator's voice makes my eye twitch. I would much rather read them than listen to them....but they have a good story and no "bad" words (like stupid or jerk).
