A Spell for Chameleon discussion

Piers Anthony appears popular. But if you've never read any Piers Anthony where should you start? Book mentioned is simply to fill the blank.

i liked his incarnations of imortality series. i loved the xanth stuff as a kid, but i tried it as an adult and it didn't hold up. i'd try "on a pale horse" if your an adult. "spell for chameleon" if your a teenager.
