Forensic specialist Laughton Rees is not ashamed of her checkered past—after all, her youthful indiscretions led to the birth of her daughter Gracie, the person she loves most in the world—but when Gracie’s father unexpectedly turns up in their lives again, Laughton is automatically wary.

Shelby Facer is a dangerous man, formerly imprisoned for his involvement in an international drug trafficking ring, and no matter what Laughton once felt for him, she doesn’t want him anywhere near Gracie. But when Shelby claims that he has information about an especially difficult murder case she is working, she can’t turn him down.

A body with no head or hands has recently turned up in the river Thames, and the police are at a loss until Shelby identifies the man. The victim was part of a highly secretive smuggling ring Shelby was involved with during his and Laughton’s youth—which Laughton’s father, former commissioner for the Metropolitan police, was investigating before he died.

Laughton throws herself into her father’s old files to try to trace the connections between past and present, but as she and DCI Tannahill Khan circle closer to the truth, the case becomes dangerously personal. When another body turns up, mutilated just like the first, the victim is no stranger to Laughton. She’ll have to face the darkest parts of her past to find the man behind the murders—before he takes away everything she loves.

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, tragic as it is, won't stop that mission from continuing.

So who would sacrifice twenty-two 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?
