Fantasy: from easy reading to heavy stuff
all of this are first class IMHO
-Joe Abercrombie "The first Law Trilogy" (finished)
-Scott Lynch "The Gentlemen Bastards Sequence" (first 2 (selfcontained) Books out) HIGHLY recommend
-Patrick Rothfuss "The Name of the Wind" HIGHLY recommend
-Steve Erikson "Malazan Books of the Fallen" (this will finish soon, read only if you are a fast reader or have MUCH time as this will clock in at 10 Books of 1000+ pages each)
-George RR Martin "A Song of Ice and Fire" (this take with a grain of salt as the next book in the series takes forever to get finished...., but) Very HIGHLY recommend
-R. Scott Bakker "The Prince of Nothing" (This is very heavy stuff and in my experience a hit-or-miss Thing. If you get it, you will love it)
oh and i can second Glen Cookand Dune, but avoid Xanth like the PLAGUE.
