I continue to edit Babel. At the moment I’m checking for character. Are the characters consistent? Do they grow? Are they rounded. When I use dialogue, does it sound like their voice?
I really do find it useful to check for one thing at a time, though I’ll often notice other things apart from what I’m actually looking for in a particular edit. So, writing always become rewriting.
There is the danger, I suppose, that after a while you become jaded and cannot see the major faults. In any case, though, you edit from big picture to smaller detail. You get rid of the real problems first and then come down to spellings, punctuation and syntax.
Yesterday, I also looked at final proofs of The Prophecy which comes out in September. I agreed with the copy-editor on all but one change. We were using Track Changes. I then accidentally “accepted all”. Fortunately, I’d got two copies. However, I was then not able to find the change I did not want to accept. I guess I just have to trust my copy editor.
