Sixteen elite Sector soldiers board a plane bound for Southeast Asia and then disappear without a trace. Infuriated and humiliated by the covert attack, the Sector deploys Agent Tate Ryan to uncover the truth and rescue her fellow soldiers.

You Have Just Been Upgraded
Over the course of her investigation, Tate learns that thousands of human locator beacons delivered to the Sector contain bombs embedded in their internal processors. The missing soldiers aren't the only ones to receive the tampered-with upgrade. Tate, too, is unwittingly injected with an altered device, transforming her from an elite warrior into a walking time bomb.

Autonomy Can Get You Splintered
Tate runs a fine line between functioning operative and rogue agent. Cross that line and she will be exterminated. As she closes in on the truth behind the missing soldiers, Tate is betrayed by her own people. The time bomb in her neck is starting to tick.

Russian Roulette
Now, risking a quick death at best, Tate hand-picks a few specialists to join her as she faces a twisted psychopath conducting horrifying human experiments, a Russian dictator intent on obliterating millions of people and his vast army bent on destroying Tate and her team.
