Cast out from Heaven and alone to wander the wastelands of Hell, the fallen angel Celestial must learn to adapt to her new reality when a pair of demonic sisters find and drag her before the first angel to fall from Heaven, Lucifer. Brutally transformed into a demonic creature of the underworld, she finds herself welcomed by her new 'sisters' and soon learns that there is more happening in Hell than even her former family in Heaven ever knew about. Upon learning of the existence of Queen Eva, Lucifer's bride created from his own rib, Celestial finds herself in the middle of a dangerous plot that could lead the cosmos to the brink of Armageddon and spell certain doom for angels, demons and the mortals caught in between. Can Celestial discover the truth of this plot and find a way to stop the end times before it's too late? *Bonus first chapter of the new novel Shadowbringer included at the end.
