Oh. Yeah. Any Jack Chalker series, now that you mention it./quote]
My first JC series that I read was the Soul Rider series which I loved up to the last book (Bleh!). I bought some more of his series and realised one thing. He's a one note writer. In all of his series, the main character will either a) change form, b) change sex, c) change form
and sex or d) swap bodies with someone else. That's story telling the JC way.
There
was one book that he wrote with 2 other authors that was somewhat enjoyable as you weren't really expected to take it seriously. Sadly, I can't remember the name of the book or the names of the other authors at the moment, but it involved a literary exercise where one author would write a chapter of a story, hand it to the next author where they have to write the next chapter and then they hand it to the next author.
It was interesting to watch each author try to write the next author in a corner with no escape. One funny sequence happened when Chalker did one of his "body switching" scenes at the end of his chapter. The next author at the beginning of the next chapter started cussing out Chalker.
