Trinity Marrow lost the battle and lost her beloved Protector. Even with demons and Guardians on her side, Trin may lose the war against the Harbinger. Bringing Lucifer back to the mortal world to fight the Harbinger might be a really bad idea, but they have no options - and only the world's most important Fallen Angel has enough power , to influence the outcome of the battle. While Trin and Zane find new and more dangerous bonds, and Lucifer raises Hell on earth, the Apocalypse looms and the world moves towards its end. Victory or defeat, one thing is for sure - no one will be the same.
