I've started revisions on the YA urban (rural?) fantasy novel that's refusing to tell me its title and so far things are going well. I've cut out the first three chapters as being the wrong place to start and now it's more firmly in the action which is good. I did find, when making the revision notes, that there were a few scenes I need to write to make sense of things but so far I'm quietly confident and hoping that confidence will tide me over during the rough bits! I'll log how long it takes me to incorporate all the revision notes so that I have some idea +/- for future novels.
I'm also working on a couple of shorts in between as a way of breaking up the work and that seems to be going well, too so I'm pleased with that.
