From New York Times bestselling and Newbery Honor-winning author Shannon Hale comes a zany picture book that pokes fun at overly gendered notions of "boy books" and "girl books" and celebrates the pleasure of a good book.Stanley's thrilled for bookmobile day--until the old man at the window refuses to lend him the story he wants, all because it features a girl. "Girl books" are only for girls, the book man insists, just like cat books are only for cats and robot books are only for robots. But after a ferocious dinosaur successfully demands a book about ponies, Stanley musters up the courage to ask for the tale he really wants--about a girl adventurer fighting pirates on the open seas--and inspires the people, cats, robots, and goats around him to read stories outside their experiences and enjoy the pleasure of a good book of their choosing.
