When Calamity lit up the sky, the Epics were born. David's fate has been tied to their villainy ever since that historic night. Steelheart killed his father. Firefight stole his heart. And now Regalia has turned his closest ally into a dangerous enemy. Once the Reckoners' leader, Prof has struggled to control his Epic powers, but has now embraced his Epic destiny. Everyone knows there's no turning back-- but everyone is wrong. Redemption is possible for Epics. And David is just about crazy enough to face down the most powerful High Epic of all to get his friend back-- or die trying.
