The Sun Eater is a series that chronicles the life of Hadrian Marlowe. The official blurb says "The galaxy remembers him as a hero: the man who burned every last alien Cielcin from the sky. They remember him as a monster: the devil who destroyed a sun, casually annihilating four billion human lives - even the emperor himself - against Imperial orders." So this is one of those series where the reader knows that the protagonist is not going to die because he is the one telling the story of his life, something I am not a fan of, but it does come highly recommended so I decided to give it a try. This is a far distant future where Earth has been destroyed and since become the basis of the dominant religion, and humanity has spread among the stars using ships capable of interstellar travel. So it is epic in scope and the quoted blurb sets the stage for big things to happen, but it all starts with Hadrian as a young noble who resents his parents and wants no part of the gilded future that is available to him.
