Last Argument of Kings by Joe Abercrombie. Currently 3-4 chapters in. Going to be interesting once I finish this since I am not sure what I should read next. There's so many other books I have to go through that I don't know where to start.
I'd take a bit of a break first, but Abercrombie's following three novels are all part of that same larger story. Best Served Cold is probably the most loosely related (though it does move forward the overall world narrative), but a lot of the main and ancillary cast members show up in The Heroes and Red Country.
