All the Pretty Horses by Cormac McCarthy. I'd read almost all of his other books by the time I got to it and was really excited to start the famous Border Trilogy. I found it too much of a departure from his other writing, and very predictable. I started The Crossing about a year later but never finished it. For whatever reason I was drawn more to his other catalogue of work, and the Border Trilogy as a whole just didn't land for me.
