A long time I was told that if I ever made it as an author, my position would be very weak vis-a-vis the publisher in some of the decisions that are made. For instance, it's very unlikely that the cover artist has actually read the book.
Evidently, that's not just a big publisher thing. The niche press doing my next book (my fifth with them) had a really cool idea today-- that absolutely contradicted the entire theme of the book. It's almost like some kind of ancient demon with really dated ideas about marketing has possessed the company.
ConCom would be a hard book not to sell, but it looks like someone is actively trying.
