It is the Doomsday of Yule—the final battle between humans and dragons. Alvin the Treacherous is poised to seize the throne and begin a reign of terror that will wipe dragons from the world forever. The only hope lies with one boy: Hiccup Horrendous Haddock the Third. With Toothless, Fishlegs, and Camicazi by his side, Hiccup must face his greatest challenge yet. Can he stop Alvin, save the dragons, and fulfil his destiny to become King of the Wilderwest? The future of both worlds depends on him. (Book 12)
