Fame and death

Trinity Marrow has lost the last battle and her beloved Protector. She may not be able to win the war with the Harbinger, even with demons and Wardens as her allies.
Bringing Lucifer into the world to confront the Harbinger is probably a very bad idea. But our heroes are running out of options – and the worst of the fallen angels is the only one powerful enough to help them win and save the world. However, it turns out that the ruler of hell has his own plans for the world, which must be stopped as uncompromisingly as the very thing he is supposed to help them face.
A new, even more dangerous bond is forming between Trin and Zayne, Lucifer is about to unleash hell on Earth, the apocalypse is fast approaching, and the world is on the brink of eternal doom. Whether it ends in victory or defeat, one thing is certain: everything is about to change.
