Hiccup is trapped aboard The American Dream II with Fishlegs, Camicazi—and a ship full of enslaved Wanderers. To make matters worse, they’re surrounded by freezing waters teeming with vicious Polar-serpents, and under the watch of the ruthless Norbert the Nutjob. Hiccup has promised to help everyone escape… but how can he save himself, his friends, and 122 prisoners without alerting their terrifying captors? It’s going to take all of Hiccup’s courage, cleverness, and a bit of luck to pull off the impossible. (Book 7)
