Firefight

Steelheart is dead, and David Charleston has lost the one purpose that drove him for years. He spent most of his life training to kill the invincible Epic who murdered his father, and now that the job is done, the certainty that came with it is gone too. David has started to doubt what he and everyone else believed about the superhumans who rule the world.

Someone may be able to give him real answers: an Epic known as Firefight. David's suspicions point straight to her, and they also point to the place she calls home, what was once New York City and is now a drowned, flooded ruin. He travels there with the Reckoners, the team that hunts Epics, hoping to learn what truly makes these people what they are.

What waits in that city is not what he expects, and it threatens to hurt him more than any enemy he has faced so far. Firefight is the second book in Brandon Sanderson's Reckoners series, a fast-moving superhero story in which power corrupts and the line between hero and villain is harder to find than David once thought. The series continues with Calamity.
