The U.S. is at war. Many nurses have gone to the front, and there is a shortage of RNs at Spencer-which Cherry and her classmates help to fill, as they learn the skills they need to graduate. And who is the mysterious patient in the secret room that no one seems to know anything about? Should Cherry risk expulsion to save his life?

    But through a twist of fate, he lands on the secret island of Krakatoa where he discovers a world of unimaginable wealth, eccentric inhabitants, and incredible balloon inventions. Winner of the 1948 Newbery Medal, this classic fantasy-adventure is a joy for all ages.
