A biker gang, ruthless assassins, a relentless cop. For Bob Singleton, it’s business as usual.

Former black ops assassin Bob Singleton is on the road and on the run, an open CIA contract on his head. He rolls into New Orleans to visit a dead comrade’s mother and finds himself neck-deep in a neighborhood battle.

A biker gang is blockbusting – scaring people from their homes so they’ll be forced to sell them cheap. A casino boss needs the land, and he doesn’t care who his thugs hurt to get it.

Bob isn’t going to stand by while innocent people are victimized. He brings his lethal skills to bear and soon the bikers realize they have a real fight on their hands.

But bikers aren’t the only thing Bob has to worry about. The casino boss has dangerous associates, two brothers from the same deadly background as Bob. And the police are closing in, a relentless detective determined to find the man who has unleashed a firestorm in his town.

Among the flashing lights and bells of the casino slots, a showdown awaits. The bad guys in the Big Easy need to be taught a big lesson … and Bob Singleton’s the man to do it.

Blood Debt — the next installment in a stunning new action thriller series. Perfect for fans of Jason Kasper, Jack Carr, and Lee Child.

Read full series description

In the Rogue Warrior thrillers, the line between justice and survival is razor-thin, and former CIA assassin Bob Singleton knows it better than anyone. Haunted by betrayals and missions that blurred the meaning of loyalty, Singleton now operates in the shadows of a world he once served, hunted by old enemies and former allies alike.

Set against a backdrop of covert operations, dark conspiracies, and shifting global threats, the series trades the glamour of traditional spy fiction for something grittier — a landscape where violence leaves scars deeper than the ones on the surface. Singleton is no invincible hero; he’s a man worn thin by choices, constantly weighing the cost of redemption against the urge for revenge.

What sets this series apart isn't just the relentless pace or the sharp, unforgiving action scenes — it’s the raw humanity threaded through every chapter. Singleton’s journey is brutal, often bleak, but never empty. There’s a real weight to his battles, a sense that every decision could be his last, and that every ghost he carries has a name.

Drawing readers into a world of ruthless mercenaries, double-dealing operatives, and the unquiet ghosts of past missions, the Rogue Warrior books are built for fans of high-stakes espionage thrillers who crave more than just gunfights and car chases. They offer a dive into the mind of a man shaped — and nearly broken — by the very system he once believed in.

For readers who like their thrillers intelligent, ruthless, and crackling with tension, Bob Singleton’s story offers no easy answers — only hard truths and harder choices.
