Here's an interesting thing I stumbled onto. I only ever knew Orson Scott Card had written the Ender series, plus its derivatives. Well, I stumbled onto a copy of his Songmaster novel, and that is certainly an interesting one. I at first thought that it was about people and their songbirds. Little did I realize that the songbirds were actually people!! It was quite a departure from what I normally consider a true Card novel, but it was none the less enjoyable. And in an odd way, it had a bit of an Ender feel to it in some ways.
