Well ... a stage is finished. As of yesterday morning, I finished a respectable version of the last chapter of the new book - and I've since been sweeping back through the entire manuscript, tweaking here, pruning there, clarifying somewhere else, and generally doing a copyedit/proofread as I go. And I'm now declaring the first draft finished.
In a moment, I'll start printing it out, as there's no substitute for someone checking through a hard copy. I'll hand it over to long-suffering Jenny to do a layer of proofreading, and she's bound to catch some stuff that I missed.
This is, as mentioned, only the first draft, though I think it's a pretty good one. You'll be getting updates as things move along. For now, at least a tiny celebration is order while I think of the next task.
