Leif Metcalfe and his team, dubbed Reaper, need to recover the stolen, ancient Book of the Wars if they hope to stop the Armageddon Coalition and their pursuit of global economic control. But their attention has been diverted by a prophecy in the book that foretells of formidable guardians who will decimate the enemies of ArC. While Iskra Todorova uses her connections in the covert underworld to hunt down the Book of the Wars, Leif and Reaper attempt to neutralize these agents but quickly find themselves outmaneuvered and outgunned.

The more Reaper tries to stop the guardians, the more failure becomes a familiar, antagonistic foe. Friendships are fractured, and the team battles to hold it together long enough to defeat ArC.
