He’s faced terrorists, traitors, and death itself. Now John Ryder faces the most dangerous enemy of all—his own past.

When a high-level intelligence official is nearly assassinated in the heart of New York, Navy SEAL-turned-black ops operative John Ryder is pulled back into a war he thought he left behind. The attack bears the signature of The Fourth Estate, a ruthless shadow organization manipulating governments, wars, and economies from the shadows. But the deeper Ryder digs, the more personal the mission becomes.

Because the assassin isn’t just another killer—he’s Mike Mitchell, Ryder’s former SEAL brother, long thought dead in a failed raid overseas. Revived, enhanced, and brainwashed, Mike is now the Fourth Estate’s deadliest weapon. And he wants Ryder dead.

As Ryder races across Germany, Colorado, and Washington D.C., unraveling a conspiracy that spans continents and decades, he begins to realize the stakes are higher than ever. A bioweapon codenamed Tulip is poised to unleash hell on American soil, and time is running out.

To stop a global catastrophe, Ryder will have to confront ghosts, lies, and the painful truth about a father he barely knew—and a brother who may be beyond saving.

Explosive, relentless, and deeply human, Sins of the Assassin is a high-octane thriller about loyalty, sacrifice, and the cost of uncovering the truth.
