In the shattering climax of The Empire Strikes Back, Darth Vader infamously reveals his true relationship to Luke Skywalker and invites his son to rule the galaxy at his side. But Luke refuses -- plunging into the abyss beneath Cloud City rather than turn to the Dark Side. We all remember Luke's utter horror in this life-altering moment. But what about Vader? In this new epic chapter in the Darth Vader saga, the dark lord grapples with Luke's unthinkable refusal and embarks on a bloody mission of rage-filled revenge against everything and everyone who had a hand in hiding and corrupting his only son. But even as he uncovers the secrets of Luke's origins, Vader must face shocking new challenges from his own dark past.
