I'm less prepared than I was last year for NaNo. Last year, I had practically the entire book outlined and characters firmly sketched. However, last year I based the book on Lysistrata, so I had a full set of fully-formed characters and a pre-existing plot to follow.
This year, I don't have a firm handle on my main character, and I only have an elevator-pitch for my plot:
Outbreak meets Jurassic Park meets Anne McCaffery.
I think this will be a wild ride, though. I have several short stories on this basic idea that date back to when I was in high school (egad!). One of the stories in the mail right now sparked the idea of the book.
Well, I'm going to do a modicum of research on what a state wildlife officer does so there will be some verisimilitude in my book.
