I'm at right about 15,000 words overall; by the end of the week, I'm hoping to be at 20K, and the end of Part 1. At which point I'll send it to a few people to read and immediately freak out fretting about whether they like it or not. Kat has been reading scene by scene as I write them and making little encouraging noises, which is very helpful.
When my agent first suggested writing a nice thick book, maybe around 100,000 words, I felt a little panicked. And it's still a long way from 20K to 100K. But it's not feeling quite as impossible now. Whether I'll draft all that by the end of the summer.well, we'll see. I have an early American Lit syllabus to finish prepping too. :-)
