I will definitely second George R.R Martin's A Song of Ice and Fire series, I read Joe Abercrombie looking for something Martin-like and was pleasantly surprised. Both authors writings are gritty and merciless, which I enjoy.
I'm actually reading Best Served Cold at the moment, my girlfriend has now told me I cannot read it in public anymore after my facial expressions during certain scenes got us "funny looks" in Cafe Nero, lol.
The scene in question was the first of the seven, the bodyguard, where Monza smashes his hands - amongst other things. Joe is very good at imparting a visceral experience, so much so that several strangers now think I am mentally ill... lol
Personally while I find the violence horrifying and grim I enjoy it thoroughly, and find my self rather astonished that anyone considers it to be glamorizing violence frankly I feel far less encouraged to become a warrior of any stripe!
