The world is on fire, and Grigori Rasputin is just getting started. With the United States under his boot, the vampire lord turns his armies outward - hunting the Order's remaining bases and the artifacts of ancient power hidden inside them. Time is no longer on anyone's side. The Liberators and the Underworlders, enemies for centuries, forge an alliance neither side ever thought they'd need. Trust doesn't come easy when the hatred runs that deep, but survival has a way of rewriting the rules.
And Sverre's team won't be fighting together this time. Split apart and racing against the clock, they're forced to gamble on two separate plans - either one could save mankind. Either one could end it. This is the war they've been building to. This is where it ends. The explosive final chapter of the Warrior of Souls series.
