What kind of input does an author have in her cover art?
That depends on the author and the publisher. Back when I wrote category, I had very little (as in none!) input on the covers. But since I’ve been writing single titles I get a lot of opportunity to weigh in. My biggest request is always that the heroes have chest hair. It seems models are often shaved or waxed and I would never, ever write a hero who spent time doing that.
Many of my reissue covers are slick-chested guys. But the new single titles almost always feature guys with chest hair.
