The ninth book in the How to Train Your Dragon series.
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. The waters have risen, flooding fields and washing whole villages away.
But worse still, the wicked witch Excellinor has returned. Can Hiccup find the King's Things and win the sword-fighting contest to stop Alvin the Treacherous from becoming King of the Wilderwest?
