Book excerpt: Once upon a time, on a long, slow trip to Scotland, a little girl named Katerina-Elizabeth tossed her oatmeal overboard—again, and again, and again. She was a picky eater, and oatmeal was her least favorite food. And once upon a time, a small worm, no bigger than a piece of thread, swam alongside an ocean liner bound for Scotland and ate bowl after bowl of tossed oatmeal. He had never tasted anything as wonderful as oatmeal in his whole life. A. W. Flaherty and Scott Magoon unravel the Loch Ness legend in this whimsical picture book for the picky (and not-so-picky) eater in all of us.
