The long-awaited finale to Brandon Mull's best-selling series where magical candies give kids superpowers to fight evil magicians. The Blue Falcons is a secret kid's club that fights against a family of villainous magicians. Using an impressive arsenal of magical candy--including Moon Rocks, which allows someone to jump super high, and Ironhides that make someone nearly invulnerable--Nate, Summer, Trevor, and Pigeon defeated Belinda White, a sinister candy shop owner who almost seized control of their town, and her brother, Jonas White, a maniacal arcade operator who tried to turn the planet into his personal puppet. Now, the Blue Falcons must battle the third sibling--Camilla, who has brought the Dreams and Screams International Carnival to their town of Colson, California. Rumors are spreading about the new carnival. Those who visit feel compelled to return. Some who enter the labyrinthine Funhouse disappear for days. And the Big Top is said to bewitch audience members.

The Blue Falcons think they know who is responsible and are ready to fight, but the carnival forbids outside magic. Without their favorite enchanted treats, how can they salvage their sixth-grade year, rescue their families, and save their town? When nightmares and weird dreams start to plague everyone who has visited the carnival, the worlds of magic and reality are both endangered. With the help of a new magical enforcer, the Blue Falcons will need to learn to use the magic of the carnival against itself, including a host of new magical carnival candies, and tap into the power of their own dreams to battle their greatest adversary yet.
