All of these books sound so interesting... I need to get to the bookstore or library and read some of them!
Some of the books I have read are:
~ "The Lost Years of Merlin" series- the stories of Merlin as a teenager (quite humorous, but wonderful just the same), with interesting foreshadowing of his older years.
~ The Enchanted Forest books, including the "Book of Enchantments", consisting of other, smaller stories from the same fantasy land
~ "A Wrinkle in Time"
~ many "Star Wars" books- as Eowyn Skywalker stated, are very good
~ and some of "Harry Potter"
