What is the author's style in The Crossing by Cormac McCarthy?

The language and meaning of the story is somewhat convoluted, largely because of the lack of punctuation and the number of run-on sentences. Quote marks and dialogue tags are not used at all throughout the entire book. This is sometimes confusing, especially when when there is a conversation between two people. When this happens, the only division is that the quote of one character is included in an entire paragraph and the next person's quote is on the next paragraph. This paragraph division is the only clue as to the changes of speakers. The reader has to decide who is talking through clues in the dialogue. Often, the speaker will address someone else by name or refer to something specific that make it evident who is involved in the conversation.
