1. First Law cycle by Joe Abercrombie - too much violence for me is first books, but last trilogy is quite interesting.
2. Dark Tower by Stephen King - do I need to say more?
3. Old Man's War by John Scalzi, like this guy writing.
4. The Farseer trilogy and The Liveship Traders trilogy by Robin Hobb - pure pleasure.

6. Some Terry Prachett books.
Non Fiction:
1. Ghost Map by Steven Johnson, about cholera outbreak in London in 1854, but more about society and life of that period.
