Book 2 is at 45K in draft currently. Looks like it might be a bit longer than book 1, which was 78.910 words. To be honest, I'm glad I've taken a break on it. Some of the new research will really improve it.
I'm hoping to finish the draft this Summer, but I have three books to finish before September.
I'll start book 3 in 2017.
There's also some great material for a prequel story, which I may look at in between it all.
I also have work to do on Phoenix Point though. I'm currently in the early world research phase on that.
