can't stand piers anthony anymore.... but that series was pretty intriguing in some of it's concepts. too much male teenage hormone for my taste... although considering his age, it might be more of sour dirty old man hormone anymore. ^^
the m.y.t.h. series was written by robert asprin and yes you'll need two more asprin after you give yourself a headache from laughing so hard reading his books. also try his Phule series, sci-fi and quite humourous.
loved the magic kingdom for sale, sold! series. fun books. =D
ps: oh yeah, finished three more andre norton books between now and my last post. ;D i'm running out of ones i can find! ^^
