How to train your dragon

Follows the further adventures and misadventures of Hiccup Horrendous Haddock the Third as his Viking training continues and his father leads a stranger and the Hairy Hooligans to the Isle of Skullions in search of a pirate's treasure.

Reluctant hero Hiccup Horrendous Haddock III must rescue his best friend, Fishlegs, from the deadly disease Vorpentitis. The only cure is rare and almost impossible to find ... a potato. But where will Hiccup find such a thing?

Someone has stolen the Fire Egg. Now the volcano on Volcano Island is active and the tremors are hatching the eggs of the exterminator dragons! Can Hiccup return the Fire Egg to the volcano, stop the volcano from erupting, and save the Tribes from being wiped out by the terrible sword-claws of the Exterminators.

Stranded on the exceptionally dangerous, and possibly haunted, Beach of the Broken Heart, Hiccup must face Ug the Uglithug and complete the Impossible Task--or die trying. Along the way, he'll have to battle Berserks, dodge Scarers, and save Fishlegs from being fed to the Beast, all while being hunted down by an old enemy with a dark secret about the mysterious Lost Throne. With Toothless by his side, and time to stage his rescue running out, what's...

In exile, and hunted by dragons and humans alike, can Hiccup the Viking find the dragon's jewel and save the world from destruction?

"The Doomsday of Yule has arrived, and the future of dragonkind lies in the hands of one boy with nothing to show, but everything to fight for. Hiccup's quest is clear... But can he end the rebellion? Can he prove himself to be king? Can he save the dragons? The stakes have never been higher, as the very fate of the Viking world hangs in the balance!" --
