Just read The Sisters Brothers, by Patrick DeWitt. It's on the Man Booker short list, and is a tale of the American Wild West, the Gold Rush and the lives of the eponymous protagonists. It's a good read, but I'm not sure that it's great literature - I would prefer to have reread Peter Carey's True History Of The Kelly Gang, which was set in a different continent in the same era, and is wonderfully written.
