The How to Train Your Dragon series chronicles the adventures and misadventures
of Viking underdog Hiccup Horrendous Haddock III and his dragon,
Toothless. In Book 9, a dragon rebellion is coming–filled with the meanest,
nastiest dragons in the Archipelago. Razor-wings, Tonguetwisters, and Vampire
Ghouldeaths are attacking Vikings and seem to be seeking one soul in
particular: Hiccup Horrendous Haddock the Third! Only a King can save
them…and only a champion with all of the King’s Lost Things can be King. In
his adventures, Hiccup has collected quite a few “things” himself.
But can a scrawny Viking save the entire Archipelago from certain doom? To find
out, Hiccup will have to outwit a witch, fight his arch-enemy, and beat back an
army of bloodthirsty dragons with just one sword.
