Hiccup is captured によって Viggo's men and tortured. This is all based during Enemy of my Enemy. This is what I believe would happen if Dagur didn't get Toothless fast enough.

Hiccup didn't see the point in stopping Astrid as she ran off towards his village—towards his father—with his most desperately protected secret. He was leaving anyway. A coming-of-age tale. Deviates from movie. Borderline bromantic-comedy.

This is book 2 of a planned trilogy. Hiccup and gang is shipwrecked on a strange Island known as the Outcast Lands. Here they must survive some dangerous new dragons, an evil witch, and a mad Viking with a grudge against Hiccups.
