My favourites of fantasy are:
Sara Douglass' Troy Game quartet. A brilliant set of books which displays how much she has grown as an author, it is set at first in ancient greece but later moves to albion aka ancient england.
China Mieville's Bas Lag series. The first one known as Perdido Street Station is one of the best book ever, it is like a gritty yet fantastical version of all the big cities in the world. His second one The Scar is even better and needs to be read to be believed, however it is veeerrry dense reading.
Steven Erikson's Malazan series. Woohoo, great, fantastic, what can I say? Read these! The interplay of cultures, sorcery, and politics is very intriguing. Also veeerry dense.
Janny Wurts' & Raymond E. Feist's Daughter of the Empire trilogy is great, definitely enjoyed the bug people(what were they called again?).
Guy Gavriel Kay's Sarantine Mosaic is also coolness.
Robin Hobb's Farseer, Liveship and Tawny Man trilogies are great there is so much in there, my absolute favourite.
George R. Martin's Song of Ice & Fire is really good, its almost a mix between Robin Hobb's and Robert Jordan's styles but argh he is taking so long to write the next one
