The Lincoln Highway is the second novel I've read recently where dialogue is indicated by an em-dash at the beginning, and no closing punctuation.
I'm finding it difficult to feel any closeness to the speaker. It's as though the speaker whispers or speaks hoping I won't hear.
Does anyone else find this form odd? Here's a quick example (the context doesn't matter):
Billy looked impressed. But then his brow furrowed once again.
---[that's an em-dash] I have learned a little about William Shakespeare, he said. Professor Abernathe calls him the greatest adventure to have never set sail on the seas.
