Every week, Willy walks through an ordinary-looking set of doors at the library, and finds himself in another world. Where will those doors lead him today? To a mysterious desert island with footprints in the sand? Down a deep, dark rabbit hole full of curious objects? Or perhaps aboard a pirate ship to stand face to face with Captain Hook? An homage to the power of reading, this book for readers up to 8—and literature fans who remain young at heart—shows Willy in scenes from The Wizard of Oz, Robin Hood, Alice in Wonderland, The Wind in the Willows, Pinocchio, and other classics. As usual, the former British Children's Laureate and Hans Christian Andersen Award–winning author-illustrator of One Gorilla brings his characters to life with dazzling, detailed paintings.
