When Toothless is snatched by Romans, Hiccup and Fishlegs set out on a daring rescue mission. But things quickly go from bad to worse—the Romans have also stolen Hiccup’s treasured How to Speak Dragonese book, and the boys are captured and dragged off to the dreaded Fortress of Sinister. With danger closing in from all sides, Hiccup must outwit his enemies, rescue his dragon, and escape a fortress no one has ever broken out of. Can he pull off the impossible once again? (Book 3)
