North Korea on the edge. A lethal bioweapon unleashed. A mission where trust is as fatal as the enemy.

A deadly secret inside the Hermit Kingdom has been exposed—the regime is unleashing a catastrophic biological weapon against its own citizens. What is this weapon? How was it obtained? And most importantly, what is the ultimate goal?

Once again, Adam Knight is enlisted by the mysterious Penumbra Division. His task: uncover the truth before the weapon's full force is turned on the world. In a nation shrouded in secrecy, Knight's only entry is through an alliance with a former Russian operative. Can he trust the enigmatic figure, or will she lead him into a trap?

As Knight probes deeper, he is drawn into a fatal game with formidable foes who will stop at nothing to keep their secrets. With the clock ticking, the threat of a global disaster looms larger with each passing minute.

Knight must navigate dangerous terrain, evade deadly threats, and expose the conspiracy before it's too late. But in a world where trust is a luxury, every move could be his last. Will Knight prevail, or will his failure mark the beginning of a new war?

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