Prepare for high-flying adventures with Hiccup, Toothless and the rest of the Dragon Trainers. Meet new dragons, learn the secrets of the legendary Boneknapper and see what is in store for the holidays on the festive island of Berk.
When Hiccup and Toothless discover an ice cave that is home to hundreds of new wild dragons and the mysterious Dragon Rider, the two friends find themselves at the center of a battle to protect the peace.
Dagur the Deranged escapes from prison and ventures in the uncharted territories to build an armada against Hiccup and his Dragon Riders. Coming across a cylinder (christened "Dragon Eye") that provides information on the uncharted territories, Hiccup and his quirky team search the region looking for both Dagur and hitherto unknown species of dragons, eventually leaving Berk to build for themselves a new and distant base of operations called Dragon's Edge.Written by
