Sequel to "A Viking Chief's Twins": War of Oni & Dragon

Hiccup is tired. Tired of being forced into the role of Viking Chief, tired of feeling like he has no control over his destiny as everyone he knows expects and wants him to be chief of Berk, tired of a stupid Green Brat trying to drive a wedge between Hiccup and his twin brother Kai, and most of all tired of feeling like his passions and desires have no real purpose since the Grimborne's defeat.

So when the Ninja come to Hiccup asking for his help and offering the chance to go to Ninjago? To explore an entire new land and culture with his friends? To finally help his brother? Hiccup doesn't hesitate to say yes.

What follows is an adventure with stakes higher than the fate of dragons, but the fate of Ninjago, good, and their very ways of life hang in the balance. This mission is tough, but the riders are ready to give their lives to help the Ninja save the day. Because as everyone knows.

Dragon Riders never quit!
