Just printed off a copy of the ms. - it's up to 279 pages on my computer now, about 69,500 words. My contract originaly said 82,000 words but the editor said he'd adjust it to 75,000, which I expect it will be by the time I'm finished. They have also agreed to remove the limit on the number of books I can buy at the discount, though they weren't willing to lower the discount at all. I'm still happy. And my editor said there would be more room to negotiate on a second book. I have some ideas floating around in my head for a sequel already. So, we shall see.
I'm going to sit down with the hard copy now and see how the changes I made fit, then make a few more probably. So .. off to work.
