Paramount Vantage scoops up King Dork

I read King Dork recently, and I enjoyed it. As someone who doesn't like Catcher in the Rye at all, but has been told "Well, it's a boy book," I liked the fact that the male narrator of King Dork didn't like Catcher either. Because, after all, saying that something is a "boy book" or a "girl book", as a way of explaining its appeal, is actually a bad way of doing that. Why do we feel the need to gender pigeonhole books? I admit, I've done the same kind of thing, with working on Popular Paperbacks and such, but I don't think I've ever said, "I didn't like this book, but it's because it's a boy book."
