Casino security guard Justin Taylor is shot by a person unknown. But there’s something the shooter doesn’t realize – Justin is a friend of Bob Singleton. And now Bob’s in Philadelphia looking for payback.
Bob discovers that Justin had been watching timid bank clerk Arthur as he laundered money through the casino.
Arthur is being used by a ruthless gang of bank robbers – he was the inside man on their last heist. Tragically, Arthur is doing it all for love – he’s being manipulated by the beautiful Tiffany who pretends she’s a girl next door but is actually colder than Philly in December.
Bob confronts the gang – at just the wrong moment. Turns out the money they robbed belongs to a major crime family who’ve finally caught up with them.
Things are looking bleak in a mass-execution kind of way when quick-thinking Tiffany makes her pitch – her gang will repay their debt tenfold by knocking over a mafia-run poker game. She and Arthur will remain the gang boss’s hostages until he gets paid.
Bob can’t let Arthur die and so is forced to help execute the high-risk robbery.
Caught between warring gangs, desperate to avenge his friend, Bob realizes there’s only one way forward – dealing up some deadly justice.
The series
Some battles never truly end — they just change shape.
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.
