What is the author's style in Nightwoods: A Novel by Charles Frazier?

The story is presented in a very informal style that is fairly easy to read though there are some interesting quirks in the story. The author does not use quotation marks at all. There are statements that seem to be direct quotes but most are referenced by dashes at the beginning of the statement. In some cases, a sentence begins with, "Said" and a statement that seems to indicate a direct quote. Some readers may find the style disconcerting though readers should pick up on the style fairly quickly.
