Lady Death: Judgement War #3

With the forces of Hell defeated, Michael and his angels lead an all out assault on Lady Death, little realizing that she has already left to storm the gates of Heaven. Lady Death brings down Heaven's walls and confronts God himself, quickly realizing that he is actually Lucifer in disguise (God hasn't been in Heaven for a very long time). Lady Death kills Lucifer and destroys the Jehovex Machina that powers the realm. With both Heaven and Hell taken care of, Death sends Lady Death back to Earth to prepare for the creature known as Armageddon.
