The evil skull-faced sorceress, Deorwynn, has become unstoppable. Siphoning the blood of innocent victims, using it as an endless supply of fuel for her dark magic, she intends to raise a powerful army that will grant her the ability to conquer the enchanted realms of Novapangaea. Only an ancient jeweled scepter capable of enhancing and focusing the magic of those who oppose her might possibly counter her devilish sorcery. The only one who could use such a potent weapon is Mariposa, the Butterfly Princess, who has vanished without a trace along with her beloved Four and the clairvoyant Talla Unica. Their remaining friends quickly realize they may never succeed alone. It falls to Mirabel, Brian, Arienne, Jenna, and the others to begin their most desperate quest--joined by newcomers Fairweather the four-armed giantess and Guzzler the goblin--in which dangerous secrets are revealed, allegiances are tested, and lives are lost as they scour the globe aboard a mysterious flying castle which seems to depend on the positive emotions of its crew in order to function properly.
