After his death, Lucifer, King of Hell, leaves his four generals, the Horsemen of the Apocolypse, to deal with the aftermath. Not only trying to figer out who killed her father, Thanatos must deal with the Court that makes nightmares hide; run-away creatures of myth and legends; and outside threats from every corner and turn. But what Thanatos doesn't know, that the Seven Deadly Sins that served her father and Hell itself are rising up and gathering their strength for one last stand that could win them the throne, could kill her and the few she holds dear. A kingdom of fire and despair without a king is thrown into chaos that only Death herself can save them from. But what happens if she can't?
