Yes, I haz book deal is all very well, but now comes the hard part: writing book 2. I've written about 5,000 words (out of around 90,000) and I have an outline, which is good - I know the whole shape of the story and what's going to happen at key points, and I know the emotional arc of it (which is more than I did with the last one at the beginning). The main character is pretty clear in my head too. But I'm still getting to know the others.
That sounds pretentious, right? I should say that I'm still making them up. But so much of inventing a character is unconscious (it seems to me) that it does feel as if they have a life of their own. At the moment I'm nervous because they're still strangers to me: I don't know enough about their backgrounds or what they want out of life or how they'll react in given situations. But I'm confident that that will come. Provided I just sit down in front of the (scary) empty page, and keep writing ... wish me luck!
