Talking cats, a missing princess, swordfights with villains, and secret identities combine in this epic tale of bravery and self-discovery on the high seas. Duncan is very smart. He also has a most unusual gift. So why does his mother encourage him to be perfectly average and insist he only get mediocre grades ? His special talent is the ability to talk to cats--but Duncan longs more than anything for academic success. When Duncan rebels and gets a perfect test score, people start taking notice of him. And it turns out that some of those people may not have the best intentions . . . not by a long shot. From the same author of The Secret of Zoom and Emmy and the Incredible Shrinking Rat, Lynne Jonell delivers another magical and unforgettable adventure in The Sign of the Cat.
