When you have had enough of traditional fantasy, I'd suggest that you give "Last Call", by Tim Powers, a try. It is urban fantasy, which means it takes place in more or less the present day, but pulls its themes from mythology and legend, including the legend of the Fisher King. Then, when you've read that, read his "Expiration Date", which will not seem like it has anything to do with "Last Call". Then, after that, read "Earthquake Weather", which pulls the first two books together and completes the trilogy.
Just my two cents' worth.
