After years of devotion to the Guard, Ethan is rewarded with an apprentice. Should he train her well, he could be awarded the Guard's highest honor; the power of flight. His only concern is that is would-be apprentice is Isabel Beckett, the kid sister to his former best friend Matt. Isabel spent her childhood chasing after Ethan, Matt, and their friends, wishing to be included in their adventures while harboring a not-so-secret crush on Ethan. He remembers her as a pest, and knows that Matt, who believes Ethan is after his girlfriend, will make training difficult. After overcoming multiple difficulties, including accidentally showing one of his powers to his history teacher, Ethan and Isabel reconnect and form a strong friendship. They succeed on several missions, revealing other members of the Named along the way. Isabel's crush on Ethan grows and then dwindles as she gets closer with Arkarian, and her passion for the cause and her skills makes her a powerful member of the Named. With the prophecy slowly being fulfilled, more identities of the Order are made known. Ethan and Isabel learn that Marduke, the monster of Ethan's nightmares, is actually a member of the Order, who holds a vendetta against Shaun, a former member of the Named. In an effort to speed up the prophecy, Marduke challenges Shaun to a battle, where the members of the Named face off against Marduke and his best soldiers.
