Steelheart (Reckoners, #1)

Ten years ago, Calamity came. It was a burst in the sky that gave ordinary people extraordinary powers. The awed public started calling them Epics.
   Epics are no friends of man. With incredible gifts came the desire to rule. And to rule man, you must crush his will.
   Now, in what was once Chicago, an astonishingly powerful Epic named Steelheart has installed himself as emperor. Steelheart possesses the strength of ten men and can control the elements. It is said that no bullet can harm him, no sword can split his skin, and no fire can burn him. He is invincible. Nobody fights back . . . nobody but the Reckoners.
   A shadowy group of ordinary humans, the Reckoners spend their lives studying Epics, finding their weaknesses, and then assassinating them. And David wants in.
   When Steelheart came to Chicago, he killed David’s father. For years, like the Reckoners, David has been studying, and planning, and he has something they need. Not an object, but an experience.
   He has seen Steelheart bleed.
   And he wants revenge.
