Outside the gigantic Mountain Lion Casino & Resorts, Will Slater–fresh off a brutal career as a government assassin–watches a young child get snatched off the street by an army of security. Acting out of instinct, he hurls himself into the fray, rescuing the girl and preventing her from a fate worse than death. Shien carries sensitive information capable of bringing down Peter Forrest, the billionaire owner of Mountain Lion. When Slater opts to protect her and pursue the truth, he unravels a horrifying discovery that will unlock his deepest, darkest rage.

Half a year ago in Macau, Will Slater waged war to rescue nine-year-old Shien from the clutches of a hellish industry. He left her with an old government colleague, who promised to find her a foster home and give her some semblance of a normal upbringing. Slater moved on... Now, deep in cartel-infested Colombia, he hears dark whispers of something called the Lynx program–a clandestine division that raises young girls and forges them into sociopathic killers. A division founded by the very same man Slater left Shien with.

In the neon-drenched alleys of Budapest, Will Slater comes face to face with his past. Jason King is back–and he brings devastating news. When Slater agrees to help King get revenge, they quickly find themselves in a fight they know very little about. Because the world is changing and technology is rapidly advancing, spiralling toward a total transformation of society. There is a new breed of terrorist–the next step in human evolution. As the truth unravels, the terror amplifies. And by the time it's over, they both find out that there is a fate far, far worse than death.

Will Slater needs to lay low. With the whole U.S. government antagonised by his recent actions, he smuggles himself to rural eastern Zimbabwe and tries to keep his head down. But that was never going to happen. Whispers and rumours of a gang of psychopaths sweep across the plains. Remnants of the old regime, cast out from the previous dictatorship, continue to wreak havoc. They’re armed to the teeth and their manic leader is untouchable. They own this territory, and everyone in it.

Aboard a luxury passenger train in the desolate Russian Far East, Slater heads for the port city of Vladivostok with a mysterious grudge. After traumatic past events, he was reluctant to return to the region, but he’s got unfinished business to attend to. Terrified passengers, secret police, and shadowy underworld figures are just the beginning. Arriving in Vladivostok, he finds something wretched–something dark, twisted and shocking.
