With all the books I've read, only a few could make a good "foundation" for a mud. As stated before, what makes a book good to read is character interaction. Who would read an Eddings book if Sparhawk was a bit more of a git? With that said........

What books I wouldn't mind seeing turned into muds, or even cartoons for that matter are the books written by Elizabeth Moon. Particularly the Sheepfarmer's Daughter trilogy. She made those characters stand out. >.> <.< ^.^
