Just wrote the end to episode 01 and ended up at almost 20000 words. It'll increase during the first edit when I add more details and I'll likely encounter a plot hole or two to fix. Even though I tried to keep track of things.
It also ends with a little cliffhanger to my pleasant surprise. And the reader's frustration. ;-)
I was waiting for the site with the longest approval time to approve my latest two submissions there and keep everything in sync, but it looks like I'll post the last chapter of Meeting the New Enemy tomorrow anyway.
