Book Description: Winner of the Caldecott Medal One day, a small boy receives a very special invitation -- the King and the Queen have invited him to the castle for tea. He accepts, with one question: "May I bring a friend?" "Any friend of our friend is welcome her," says the King. But their guest's friend turns out to be someone they never expected! Beatrice Schenk de Regniers's rhythmic text and the fantastical, jewellike artwork of Beni Montresor have made this book a favorite for more than twenty-five years.
