It is the Doomsday of Yule. At the end of this day, either the humans or the dragons will face extinction. Alvin the Treacherous is about to be crowned the King of the Wilderwest on the island of Tomorrow. His reign of terror will begin with the destruction of dragons everywhere. The fate of the dragon world lies in the hands of one young boy as he stands on the nearby isle of Hero's End with nothing to show, but everything to fight for.

Hiccup Haddock Horrendous III was a truly extraordinary Viking hero. The warrior chieftain and awesome sword fighter was known as 'the Dragon Whisperer', on account of his power over these terrifying beasts. But it wasn't always like that, and this is the story of his rise to fame, in his own words.

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

The story continues in the ninth volume of Hiccup's 'How to Train Your Dragon' memoirs. Bad times have come to the Archipelago. Ever since the woods of Berserk burned down, it is almost as if the world is cursed. Dragons are starting to revolt against their masters.

Hiccup has three months, five days and six hours to discover America, get back to Berk, save his father, battle Polarserpents, and win the annual Inter-Tribal Friendly Swimming Race. Can he do it?

A brand-new HOW TO TRAIN YOUR DRAGON spin-off series, starring Hiccup and his fellow Warriors-in-Training in hilarious, hair-raising adventures.
