Teh RR Martin

Just finished A feast for crows. Waiting for the 5th book to A Song of Fire and Ice.
Anyone recommend me some good fantasy content?
Looking for mature content, aka no tad williams.

Its strange how polarized the two series, goodkind vs martin, are. My friends who like one dislike the other intensly. It may just be my friends but ive found that the ones are like goodkind tend to not be as literary or philisophically deep and the ones who enjoy goodkind more do not read as much or think critically. The goodkind friends also seem to get drawn into the whole ayn rand way of thinking thanks to goodkind. :(
