Continuation of Rivalry. Hiccup has been given the task of training the Flightmare to clear the Hofferson name. First, he has to see to integrating dragons into the daily life of Berk, and then he has to make it through the winter, all while recovering from losing his leg. Luckily he has a Night Fury and an odd assortment of teenagers to help him.

Astrid's family has been after the throne of Berk since it's founding. Finn Hofferson was intended to take the chiefdom, but his unfortunate fate with the Flightmare tarnished the family name. Looking for redemption, and with parental pressure, Astrid takes it upon herself to put Hiccup in his rightful place, until he suddenly thwarts her every attempt to rise in Dragon Training.
