Re: Logen Ninefingers and the rest (spoiler alert)
I love all the unanswered questions because I think that means I will be treated to more books by Joe Abercrombie. He is fast becoming one of my favorites. The dark fantasy books are my favorites and First Law was a home run for me. I think you are really going to enjoy Best Served Cold too.
Other dark fantasy that I have really enjoyed are the George Martin novels, Carol Berg's Rai-Kirah series, anything by Fiona McIntosh, and Brent Weeks Night Angel trilogy.
