Every Mission Has Led to This. Every Enemy Has Been a Shadow of the Real Threat. This is the Endgame.

Adam Knight was supposed to recover. After years of dismantling global conspiracies, Penumbra Division ordered him to stand down. But Knight never stopped hunting.

While officially sidelined, he’s been tracking Rubicon—the shadow organization behind every crisis he’s helped avert. Just as he’s summoned home to determine if he’s still fit for duty, a tip from an old friend changes everything: a deadly enemy Knight once defeated has resurfaced after being on the run since their last encounter.

Operating outside Penumbra Division for the first time, Knight forms an uneasy alliance with the war criminal. The deal is simple—work together to infiltrate Rubicon or watch the world burn.

But Knight isn’t the only one hunting. Penumbra Division is closing in on Rubicon too. Former colleague Jessica Feeney follows her own lead, uncovering an IT company that may be the key to the shadow organization’s infrastructure and the power behind it.

A race around the globe is on to uncover Rubicon’s endgame. What they discover is chilling. A new weapon. One so unimaginable it can destroy the world order with the press of a button. Every conspiracy Knight has dismantled leads here. And he’s ready to pay any price to stop Rubicon. But will his sacrifice be enough?

If the high-octane narratives of Tom Clancy, Lee Child, Robert Ludlum, Vince Flynn, and Ian Fleming keep you turning pages late into the night, then prepare to be engrossed by the world of Adam Knight.
