In this gripping medieval page-turner, Roger and his sister Alice are kidnapped and held for ransom in an ancient tower. To escape and find their uncle, the children must summon all their courage and imagination. "Designed as easy-reading material for middle-graders, this has the virtues of an attractive format and illustrations, a fast plot, and even a feminist fillip: Alice is the more intrepid of the siblings, Roger's gifts are for music and ventriloquism."--"Bulletin, Center for Children's Books.
