The Fight of the Flamestrike

Join Hiccup Horrendous Haddock the Third and his dragons, Toothless and Windwalker, in their hilarious, hair-raising adventures at the Isle of Berk’s Training School for Vikings and Dragons. Where they are bottom in pretty much everything.
Disastrous Lesson Number Two: Boarding-An-Enemy-Ship-At-Sea
Hiccup and his fellow Vikings are SUPPOSED to be learning about enemy ships at sea. But when they come across a mysterious vessel, with a ripped sail and nobody driving it, Hiccup’s heart sinks. There is something deeply spooky about this ship.
They really, really shouldn’t get onboard.
But… like on so many occasions in Hiccup’s life, they are going to do it anyway.
