Sentinel (Armored Book 2)

A Deadly Mission, A Family in Peril

In this electrifying thriller from the #1 New York Times bestselling author of The Gray Man series, Josh Duffy faces an impossible choice—his mission or his family.

Josh and his wife, Nikki, both work for the State Department’s Diplomatic Security Service, tasked with protecting diplomats in high-risk zones. Their latest assignment takes them to Ghana, where they’re safeguarding U.S. embassy personnel visiting a dam construction project—a symbol of American commitment to the region. With Ghana considered a stable democracy, the Duffys even bring their children along for a short vacation.

But stability doesn’t last. When a covert Chinese operation threatens to sabotage the dam in a bid to undermine U.S. influence, chaos erupts. Now, Josh and his team find themselves on the run—trapped between a deadly Chinese hit squad and a ruthless rebel army. With his family caught in the crossfire, Josh must rely on every ounce of his skill and instinct to survive.

High-stakes, action-packed, and full of pulse-pounding tension, this thriller delivers a relentless ride where every decision could mean life or death.
