The Language of the Night by Ursula K. Le Guin,on children's books,great!

All you do is take all the sex out, and use little short words, and little dumb ideas, and don’t be too scary, and be sure there’s a happy ending. Right? Nothing to it. Write down. Right on.
If you do all that, you might even write Jonathan Livingstone Seagull and make twenty billion dollars and have every adult in America reading your book!
