With Drekavac temporarily sealed away, it’s up to Luz and the reapers to rebuild their numbers and protect the souls. A task made difficult when the Reaper Council wants to oppose her at every turn. But their plans are soon forgotten when a new threat emerges in the form of demonic armies with weapons they’ve never seen before...weapons designed to take down a reaper. When hope seems lost, they discover the existence of two factions who have similar goals in mind. The order aims to protect the humans and the Sentinels aim to protect the supernaturals. Now they must find a way to coordinate their knowledge and troops in order to save the human race and Earth itself. Can they save them in time? Despite all of their strategic planning, they can’t seem to get a step ahead of the demons, revealing the existence of spies in their ranks. Spies that may just cost even more reaper lives. With the war eminent and suspicion in their numbers, they have to find out who to trust and how to survive. To make matters worse, mysterious and disturbing letters are showing up for her, and after more than one attempt to kidnap her, she learns to take them seriously. Who is her new tormentor, and what does he want her for? Can Luz save the humans and her realm, or will this be the end?
