Are you bothered by deliberate changes in voice? For example:
The girl was in great peril. The mustachioed villain had tied her to the railroad tracks. Crap, she thought. How the hell am I going to get out of this?
I'm finding first person gives insight without the constant 'she thought,' or 'she said to herself.' But I don't want to write the whole story in the character's voice. Any thoughts?
It's impossible to tell if something works from just three sentences (something you can remind me about when we do the Happy Hooker Crapometer).
That said, my vote is usually to pick one and stay with it. Leave the fancy schmancy stuff until after you've finished the entire novel and you think it doesn't work.
And one of the oddities of this blog is that no one has ever commented on my tendency to shift POV from "miss snark takes exception to", followed by "I can't stand this" in the same damn paragraph.
They chomp my spelling, my punctuation, and a lot of my 'tude; no one has ever said anything about POV. Miss Snark does not conclude it's because she is such a fabulous writer. I think it's cause people don't really notice. Perhaps I'm wrong. I bet we'll find out!
