Finished "Last Argument of Kings" by Joe Aberrcrombie - the final book in his First Law trilogy.
This was a series that got better with each book and this third one is excellent. All the characters and plots are drawn together and it never feels contrived. The plot is good - it won't astound you but there's enough decent world building in it. What's far more interesting is the visceral tone of it - Abercrombie has a way of making the world seem far more real than many fantasy series. He doesn't shirk from the violence of characters in both the real terms and their thoughts.
It's characters though that are the strongest point. It's cheap to just label them as "shades of grey" - rather he's created some real, believable people. They've got fears, hate, love, dark and good thoughts. The character of Glokta, the torturer caught up in events, is particularly interesting - bitter, self-loathing, prone to all acts of violence to keep himself alive and yet , somehow, you can still feel sympathy for the crippled body.
There's a very satisfying final battle and Abercrombie refuses to come up with a pat ending (and, of course, leaving scope to return to the world). One of the best and most satisfying conclusions to a fantasy series I've ever read.
