Well, in this case it's a book that features small sexualized female creatures, which is already pretty ick, but then you put the fact that the Eddings' went to jail on multiple charges of "extensive physical child abuse" and that's a whole new layer of closely connected grossness.

It's one thing to accept death of the author when the material isn't related to whatever it is the author did. It's a bit more unsettling when the work seems like it was influenced by those same proclivities.
