Book 3 in the Grimnoir chronicles.

Actives, people who wield a variety of powers, come from a symbiotic relationship with a being called the Power. But the Power isn't as strong as it seems, in fact it's the prey for another force. A force that has been chasing it across the worlds, devouring everything in its path. And now it's coming for humanity.

Before, the Iron Guard has defeated it, but now the Guard is infiltrated by the enemy. And the leaders of countries across the world seem to believe that Actives are dangerous, and best rounded up in camps--or worse. Maybe this time, the enemy is waging a subtler war--one the Grimnoir is losing.

Working with what they have, Jake Sullivan will have to assemble and army, while Faye Vierra makes herself into a weapon to defeat the world-killer. If they don't succeed, everyone dies--the problem in convincing the rest of the world of the danger before it's too late.

Another riveting tale, full of setbacks and hidden dangers, monsters and traitors, heroes and self-sacrifice. Sometimes it's hard to tell the good guys from the bad guys, but in the end, people are revealed by their actions.
