Hiccup Horrendous Haddock the Third—smallish Viking, reluctant hero, and heir to the Hairy Hooligan tribe—is hiding high in the Murderous Mountains with the Company of the Dragonmark. The Witch’s Spydragons patrol the skies, and Alvin the Treacherous holds the stolen King’s Things. With the Doomsday of Yule fast approaching, Hiccup must outwit dragons, reclaim what’s rightfully his, and prove he’s the true King of the Wilderwest. But with whispers of a traitor among them, can Hiccup trust anyone—or is betrayal just around the corner? (Book 11)
