I have a book which is now in the hands of a publisher. It was recently submitted so it will take quite a bit of time to hear back about publishing or not. When I submitted the manuscript it included a character that now the creator of the book wants omitted. (I am basically the ghostwriter and the one who submitted the book...it's a long story.) Now what? Do I resubmit a manuscript? Wait for a yeah or nay by the publisher? If the publisher likes the story, do I still have the option of saying the character wants to be omitted? The creator is very attached to his book and refuses to bend on this point. So, does that make the manuscript now void?No, not necessarily. I mean, it's not one of the main characters, is it?
I'd suggest you wait to hear from the publisher, and if there's interest, let them know immediately about this change. Most likely they won't have a problem with it.
And if they do, then you can assume they wouldn't have wanted the revised manuscript, can't you?
