The Sisters Brothers by Patrick deWitt
Synopsis - from Amazon
Hermann Kermit Warm is going to die. Across 1000 miles of Oregon desert his assassins, the notorious Eli and Charlies Sisters, ride - fighting, shooting, and drinking their way to Sacramento. But their prey isn't an easy mark, the road is long and bloody, and somewhere along the path Eli begins to question what he does for a living - and whom he does it for. The Sisters Brothers pays homage to the classic Western, transforming it into an unforgettable ribald tour de force. Filled with a remarkable cast of losers, cheaters, and ne'er-do-wells from all stripes of life-and told by a complex and compelling narrator, it is a violent, lustful odyssey through the underworld of the 1850s frontier that beautifully captures the humor, melancholy, and grit of the Old West and two brothers bound by blood, violence, and love.
I am a fan of Westerns, both in book form and on-screen, and had been looking forward to reading this one for a while. I was a wee bit disappointed, though. I did like Eli as a character, and there were some particular sentences that I really enjoyed, but overall it just didn't grab me in the way I had hoped it would. I have quite a lot going on just now, though, and am a wee bit distracted, so maybe at another time it would have made more of an impression on me. I wouldn't rule out re-reading it at another date, but I won't be rushing to any time soon.
