I'm up past 50000 words on the current novel, which seems like quite slow going for me, but then I've been doing other things as well. Anyway, I might as well take my time, given the queue of things stacked in front of it on the finished pile.
The copy-editor on the first novel has been in touch, explaining the process, which I thought was a nice touch. I really must remember not to be one of those 'It's perfect as it is!' authors, which should be fairly straightforward. The joy of having moved onto something else is that you lose some of the protectiveness towards the last one.
