Hilleman's new novel is World, Chase Me Down.
At Publishers Weekly he tagged ten great western novels you've probably never read, including:
Welcome to Hard Times by E. L. DoctorowRead about the other entries on the list.
Another debut by a literary heavyweight. Many have at least heard of Ragtime and Billy Bathgate. But, even among those folks, very few would think the man got his start with cowboys. The only reason this one isn’t ranked higher on my list is that it relies on boilerplate formula too often. The “Bad Man from Bodie” is a formulaic creation as far as outlaws go, but the prose with which Doctorow constructs him and his dark humor keep the character and the story fresh despite its familiar conventions. Read the first two pages and you’ll see the sure-fire signs of how Doctorow became a master stylist.
