“The bond between dragon and rider… will shape the future.” Five years after bringing peace between dragons and Vikings, Berk has become a place where the impossible feels normal. Under the leadership of Hiccup Horrendous Haddock III, humans and dragons now live, train, and explore the world together. With Toothless by his side, Hiccup journeys beyond known lands, discovering new species of dragons and hidden territories no one has ever seen. But during one of these explorations, he uncovers a dangerous secret — someone is capturing dragons to build an unstoppable army. As a powerful enemy rises, threatening to destroy the balance between dragons and humans, Hiccup must step forward as more than just a rider. He must become the leader Berk needs. Along the way, he discovers truths about his past, reunites with someone he thought was lost forever, and faces choices that will change his life.
