Chris Grabenstein (far left), author of The Island of Dr. Libris and Escape from Mr. Lemoncello's Library, visited Sacred Heart School in Havertown, Pa., where students dressed up like characters from his books. The event was arranged by Children's Book World in nearby Haverford. Grabenstein's new middle-grade novel is the puzzle-packed sequel, Mr. Lemoncello's Library Olympics (Random House).
