I recently got into Steven Erikson's Malazan Empire after ostentatiously typing "books better than Game of Thrones" in the search engine -- mind you, I really like Martin, too! I have read up until book six, "The Bonehunters" so far. It absolutely outstanding so far. Although it may discouraging for some since you really have to read the first 2-3 volumes to really grasp the story, I highly recommend it. It is some of the best fantasy I've read in years. I am also concurrently reading Abercrombie's First Law trilogy, currently being on "Before They Are Hanged". It's not epic fantasy -- it features less characters and subplots, but the ones present are really well fleshed out and I must give credit to the author for his ability of craftily using gritty atmosphere (recently highly overused, in my humble opinion, in any genre, not just fantasy) without being cartoonish. I am also really looking forward to reading the new Ralph McQuarrie book by Brandon Alinger.

I couldn't also NOT recommend Hanya Yanagihara's "A Little Life" which I believe to be one of those one in a decade titles: it's a really hard read and the catharsis at the end is debatable -- if not delusional, but I believe it's on the way to become a classic.
