I'm not really into Fantasy books, but my son really liked the Wizard of Oz series, and now we're ready to move onto something else. We also read the first three books of the Chronicles of Narnia, but they were a little slow at times. Are there any suggestions of books that will keep us both entertained? I had read the David Eddings books as a teenager, but they're probably a little too "old" for him right now. Perhaps the Prydain Chronicles, which I've never read?
