Fallen Morningstar:Lord of the Polar Night

Angel Eno loves Lucifer. To save Eno, Lucifer betrays him, falls, and lets Eno impale him—so Eno awakens as war god Michael. Michael carries the world's burden, unaware. Lucifer rules the abyss with Michael as his only weakness. When the past is exposed, they reunite and rebel against the law that made their love a sacrifice.
