I've been reading Joe Abercrombie's "The First Law" series which, apart from having absolutely top-notch titles, have produced a new character to add to my list of favorites. I speak, of course, of Sand dan Glokta, former war hero turned crippled torturer, who is unfailingly paranoid and caustic. Basically, the whole series (I'm only on the second book) is reminding me of Martin's "Game of Thrones" series, but with all the parts I didn't like removed, and Glokta particularly reminds me of Tyrion, who was easily my favorite character from that series.
The worldbuilding is a leeeeeetle thin and the characters aren't quite completely separated from their obvious inspirations (what I call "2.5 dimensional characters." Alternately: "Imperfectly-filed serial numbers.") However, I'm enjoying them immensely. They are exceedingly violent and feature graphic torture scenes, so not for the squeamish, but the books take the right approach to violence, in my mind. That is, the violence is horrific and unpleasant, and generally the characters regret it even if they win. In particular, Glokta's nuanced and terribly cynical view of his own role as torturer rings darkly true to me.
