It isn't long, though, until Sydney and Nick are called on a mission, leaving Greyson with no choice but to patiently recover and train, ready to take on Pluribus whenever he may be called. A year passes, and the country is still suffering from the fallout of the new law, with divided neighborhoods, nationwide protests, and renewed threats of secession. Even worse, Pluribus and its new Wolf teams have worked under the radar on a bold, crippling attack that they hope will send the country over the brink, spiraling to unavoidable civil war.When Rubicon finally calls Greyson to mission, he must wield new ammunition and work with friends across the country - both old and new - to face the incredible threat. In a frenzy of explosions, deadly drones, and dazzling new technology, Greyson fights the terrorists in urban streets, snow-covered mountains, and towering skyscrapers in pulse pounding action that challenges Greyson to his core.
