I absolutely love Julia. She's got a great story, and turns out to be such a badass! Did anyone (or any other characters) influence your writing of her?
I've often wondered where Julia came from. She's the most mysterious to me of all my characters. I'm pretty sure she has origins in my own experiences in my 20s, when I was living a pretty marginal life, and feeling on the outside of everything. But I'm sure bits of her came from other places too. Holden Caulfield, YT in Snow Crash, my sister (who's the mathematician of the family), Salander from the Stieg Larsson books...anybody who's ever been left behind.
