I have the main edits back for Against Gravity. These are the general suggestions from the editor concerning the plot. There's no major changes required, but what changes there are, are going to take some time and effort, at least a couple of weeks effort, possibly more. It means I can put The Fracture to the side for one moment, and come back to it later to see how I feel about it.
Mainly, I need to tighten the middle section of the novel, since there's a little too much to-ing and fro-ing. This means trimming a particular character (not the hero)back a good bit. He appears at several points through the middle of the text, so it's going to take a little ingenuity to work the story around him if he exits the story earlier than I'd originally intended.
Editors are good for this kind of thing since it can be exceptionally hard to get a complete grasp on a book you're writing. It's like not being able to see the forest for the trees. When you're working on any one particular section of the manuscript, you can see that bit clearly. It can be easy to repeat yourself, at different points, and that's one of the main things you (or at least I) can catch myself doing.
Once this is done, and once Tor are happy with the changes, the next thing will be the line edits.
