Recently finished both Dust of Dreams the ninth book in the Malazan book of the Fallen series and John Dies at the End. Finished the first book in the Elric Saga yesterday. Currently on the second book in that series, A sailor on the Seas of Fate (I think that's the title).
For a few suggestions to people looking for books I would have to go with: both of Darren Shan's series; Cirque du Freak and Demonata. Both series by Jim Butcher; The Dresden files and Codex Alera.
For the heavy fantasy fan I suggest the Malazan book of the Fallen series by Stephen Erikson, these books are amazing, and he only has one book left to write for the conclusion of the series. Another series to go with for heavy fantasy would be A Song of Ice and Fire. I might suggest the Sword of Truth series, some don't like it but I loved it.
For more of that Sci-fi feel I would go with the Dune series, only up to the Sandworms of Dune (I Think that's the title) but I've loved it so far.
