In this deadly funny fourth Tale from the Five Kingdoms, it's Gracie Gillypot's birthday, and Prince Marcus plans to show her a flight of dragons as a special gift. But when greedy, chocolate-hungry twins awaken the banished Old Malignant One, evil magic and Total Oblivion threaten the Five Kingdoms. Gracie must find a powerful, long-forgotten dragon's egg before the Old Malignant One does in order to save the day. With the help of a wayward troll, two chatty bats, and the ancient crones, can Gracie foil his rotten plans? And can she overcome a spoiled princess, a malicious crow, and loads of chocolate cake to do so?
