No comment on Ann Coulter's 'research'
Check out Russell Banks's Cloudsplitter if you're looking for a literary take on some interesting American history.
I'm more of a sucker for natural nonfiction; if you want a real feel for this great country of ours (geographically at least) pick up John McPhee's short stories to whet your appetite. His full length fiction is equally enjoyable.
I can suggest great literary fiction all day long, but I won't snob everyone to death.
