I love good books and reading them. By the time I was sixteen, I had read almost every major league baseball player's biography I could get my hands on, every science fiction short story and novel I could find, Mark Twain, Mad Magazine, comic books, Edgar Rice Burroughs, etc.
Children's literature at an intermediate reading level is a booming business and is a genre that is not familiar to many adults. By the time your child is an independent reader, you don't read with them much. Therefore, a lot of intermediate level books for children may have escaped your attention.
I have read these over and over and enjoy them every time. Check 'em out. I consider each one a treasure, a gem, a classic.
