Make the most of it. Because soon it is going to get really REAL. Because the first thing your publisher is going to do is get an editor to go over your work.
|How editors look while they are reading your book|
Oddly enough, because the publishers have bought your book (remember, you signed the contract whilst extracting tights from the dog?) the first thing they want to do is change it. Okay, they aren't changing it because it's not good, or they had a quick whim that they wanted a book that was almost exactly like yours only completely different, but they are changing it because they think it will be better done a different way. Or with more characters. Or less. Or located in Dorset. Enid Blyton's 'Five Go To Smuggler's Top' was originally called 'Four Go To Hayling Island' before the editors got their hands on it, you know.
|Except none of the editors knew where Hayling Island was, so it had to go...|
In essence, your editor is going to make you rework your book. It's going to be like doing the ironing. Hopefully it won't be more than smoothing out a few creases and getting the corners to lie flat, but it might be the literary equivalent of putting the pleats in a kilt and 101 Ways with a Lace Collar.
|I've never ironed anything, but I understand this is a suitable analogy.|
Oh, and don't turn your editing iron up too hot. Nobody wants a melted plot device.
