Once lost to history, the Book of the Wars has resurfaced, and its pages hold ancient secrets and dangers. Former Navy SEAL Leif Metcalfe has been tasked with capturing the ancient text, but a Bulgarian operative snatches it, determined to secure her freedom. When a series of strange storms erupt, they must form an alliance to thwart impending disaster.

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. But as this millennia-old conspiracy creeps closer and closer to home, the implications could tear Leif and the team apart.

Sometimes, the only hope is the enemy. Leif Metcalfe is done waiting for answers and seizes control, a move that comes with a high price and a deadly risk: teaming up with the enemy. He can only hope that what he uncovers will heal the wounds he's inflicted on those he loves. Iskra Todorova believes Leif is on a collision course with death and knows firsthand the irrevocable cost of that path to the soul. While trying to protect her daughter and intervene with Leif, Iskra is forced to set her sights on the man behind the evil organization ArC—Ciro Veratti. Torn apart by injuries and opposing views on how to handle Leif's act of treachery, team Reaper hunts one of their own. The only thing they agree on is not stopping but starting the final battle prophesied in the Book of the Wars.
