Inheritance

A teenager named Ned must deal with the realization that his father was secretly the world's greatest hero, the Zar. This realization is short lived when his father is impossibly killed by assassins. Coming to terms with the loss of his father is even harder because Ned's older brothers think they should have inherited these mighty abilities instead. Now hunted by his father's killers, regardless of the fact he doesn't have any idea who they are or how to control the superpowers he's inherited, Ned must learn quickly or die just like the hero who came before him.
