My guess as to why Phil didn't draw the covers of the novels is that, by creating the novels, the Foglios were hoping to tap into a new market, a market of people who don't like graphic novels and might be turned off by Phil's very cartoony, comic-book style of art.

The Foglios have stated that this was one of the reasons that they wrote the novels, if I recall correctly, but I don't have the time now to dig up a reference to support this contention. I have no idea how successful they have been in reaching new people with the novels.

By the way, personally, I hate the novel cover art work.
