I don't care if this passes as satire or fiction or fact, it was a good read. I loved it :-)

Issac Asimov had a great series called Lucky Star (6 books) that were great as a young teen growing up in the 50's and 60's and as said previously Heinlein and Herbert. C.S.Lewis The Chronilces Of Narnia is one of the best Fantsy books for kids. Also Piers Anthony's Myth series.
