HOW TO SPEAK DRAGONESE (HOW TO TRAIN YOUR DRAGON)
The story begins when Hiccup, his friend Fishlegs, and his cranky dragon Toothless get separated from their class during Boarding-an-Enemy-Ship practice. They accidentally board a prowling Roman galley intent on provoking war. When they rescue a tiny nanodragon, they uncover a plot to steal every dragon on the Isle of Berk.
