It's been six months since the Quest Kids--Ned, Terra, Gil, Boulder, and Ash--saved a village from a furious dragon (no big deal) and turned their questing efforts toward finding Ned's parents. But when the crew notices a serious sense of doom and gloom across the Seven Kingdoms, they set out in search of Doug, whose mysterious Dark Prophecy has the potential to send the world into even more dire darkness and dread.

With help from new and old friends, the Quest Kids sail through stormy seas, vacation on the newly rebranded Contentment Island, and venture into the Forsaken Lands to find Doug, whose wicked tunes and even wickeder plans are in full force. Can the Quest Kids get it together to counter Doug's plans and find Ned's parents--or must they watch as a triumphant Doug surfs on waves of fire and fulfills his terrible prophecy?
