Outside, World War II rages as German planes drop bombs over London. Inside one family's home, a boy lies gravely ill in bed. Before leaving to fight in the war, his father told him about Davin, a teddy bear that holds the power to make sick boys well. But things look bad—no one knows where Davin is. In an attempt to save their friend, the miniature figures of a little Bugle Boy, a blustery Sergeant Major, a princess, Robin Hood, Chingachgook, and Perseus, the Greek hero, come to life and join forces to find the mysterious Davin. Along the way, they encounter a ferocious cat, a man-eating spider, the Dark Knight, and Blackbeard and his band of terrifying pirates. As read by Grandma Goddess to her grandchildren, Davin is a story within a story, a fantasy in which literary and historical characters clash in a war between good and evil to save a child's life.
