For much of her seven years of age, Ava Appelsawse has wanted a baby sister. Or a dog. She would have settled for a cat. Instead she got a hamster...and an unexpected gift. A stack of wood left behind by a neighbor from which her father crafts a toy castle. It is perfect for games of make believe royalty with her dolls. And as she comes to learn, the castle is able to set her forth on adventures that are nearly beyond imagination.
