Ok, looking for the name of a pulp fantasy book I read close to 20 years ago.
Standard plotline, young man from this world ends up in the fantasy world, but it turns out that he is very important. The magic in the fantasy world runs off of poetry, and because it is very dangerous to just make up new magic “spells”, his making up poems on the fly to get things to happen is considered dangerous and unstable.
Funny, clever book, but I just can’t remember who wrote it or what is was called.
He also wrote two other very interesting series:
The Xanth Series
The Incarnations of Immortality Series
