How to Betray a Dragon's Hero

Hiccup Horrendous Haddock the Third is a smallish Viking with a longish name. Hiccup's father is chief of the Hairy Hooligan tribe which means Hiccup is the Hope and the Heir to the Hairy Hooligan throne - but most of the time Hiccup feels like a very ordinary boy, finding it hard to be a Hero. High up in the treacherous mists of the Murderous Mountains, Hiccup and the Company of the Dragonmark are in hiding. The witch's Spydragons are guarding the shores of Tomorrow - but Hiccup is determined to become King of the Wilderwest. Can Hiccup dodge the dragons and steal the King's Things back from Alvin before the Doomsday of Yule? And is there a traitor in Hiccup's camp who in the end will betray them all?
