Yes, Read ASoIaF!! it's outstanding and in my view the best fantasy I have ever read, perhaps even the best thing I have read full stop. While complex, it's not hard to follow as it's so well written. it's lush, it's harsh, it's twisty and it's hard to find a good read for me in comparison now days
. GRRM is a writer that seems to have easy to read detail, flowing script, fleshed out interesting characters by the bucket (which other authors sometimes struggle to do) and advanced plots.
