It's not that I didn't like this. I did! It was fun! It's just that I read it right after Lonesome Dove and Blood Meridian, and how do you follow that? Y'know?
But it's charming and funny, a nice break from the horrors of those other two. (Constant horrors for McCarthy, occasional but more personal horrors for McMurtry.) It's about two brothers named Sisters who are assassins and tooth brushers. Eli is a pretty great character, a cold-blooded killer constantly worrying about his weight and whether he's hurting anyone's feelings, including horses.
After a few days' thought, I'm bumping this to four stars. Four stars for recent literary fiction that's very good at its job. It's still not much more than a pleasant book, but there's nothing wrong with that.
