I have started compiling a list of possible titles.
Most of the time, I don't do this until I've written the majority of the work. And when I do start thinking of titles, they're all silly, to my ears anyway. At least I know I'm not going to go with one word titles. Unlike other kinds of titles, they sound particularly random--as if the author had just picked a word out from the dictionary.
On the Nanowrimo forums, I also have started to hint more about what I may be writing. Character-driven narrative mixed with a Lovecraftian plot. I think I will concentrate on the female main character. However, I'm not sure what point of view I should use. I think it'll lend an interesting tone if I use first person, but at the moment I'm leaning toward third because first person is extremely difficult to get right--I'd have to avoid trying to sound like me. And this character is nothing like me.
