Book excerpt: Read the book that inspired the famous film franchise in this wonderfully funny picture book. Before Shrek made it big on the silver screen, there was William Steig's SHREK!, a book about an ordinary ogre who leaves his swampy childhood home to go out and see the world. Ordinary, that is, if a foul and hideous being who ends up marrying the most stunningly ugly princess on the planet is what you consider ordinary.
