It starts with the destruction of a US Coast Guard cutter and the loss of her entire crew. But the USCG Claiborne was on an innocuous mission to open a sea lane between an oil field off the coast of South America and the refineries of southern Louisiana. The destruction of the ship won't stop that mission from continuing. So who would sacrifice 22 men and women just to slow down the plan? That's the question plaguing Jack Ryan Jr. He's in Guyana to work a deal to get his company, Hendley Associates, in on the ground floor of this new discovery, but Russia’s Wagner Group and a pack of Venezuelan narco-terrorists have other ideas --- and will risk war with the United States to see them through. It's up to Jack to identify the killers before they draw a bead on him, but how can he do that when the line of demarcation between friend and foe is constantly shifting?

The vibrant economy of the new Vietnam is a shiny lure for Western capital. Companies are racing to uncover ideal opportunities. Not wanting to be left behind, Hendley Associates has sent their best analyst, Jack Ryan, Jr., to mine for investment gold. And he may have found some in a rare earth mining company: GeoTech. But a trip with a Hendley colleague to the Highlands to observe the company’s operations takes a treacherous turn when their helicopter is shot down. Some things haven’t changed, and Vietnam is still the plaything of powerful neighbors. The Chinese are determined to keep Jack from finding the truth about what exactly is being processed at the isolated factory. Now Jack is in a race for his life. He has to stay one step ahead of a pack of killers while supporting his wounded friend.
