Red Country by Joe Abercrombie
So then Joe took his barbarians into the realm of the classic Western, and it was kinda awesome!
A caravan of merchants, misfits, and those who have lost something important head out into the badlands of wherever. They have a few folks with mysterious pasts along for the ride. After a few adventures they arrive in a depraved town that is caught in the midst of an underworld conflict between two bosses. Our heroes pick sides, get involved in the wild west range war that ensues. Everyone mostly loses, but there are some great heroics along the way.
And yes, Logan is here, if you are an Abercrombie fan. Good times.
