Rate this book
The BRAND NEW, action-packed Ryker thriller from million-copy bestselling author Rob Sinclair.

His past is coming back with a vengeance…

Ex-intelligence agent James Ryker has done many things in the past he’d prefer to forget. The last time he saw Gregor Minko - son to one of Ukraine’s most dangerous and politically influential arms dealers – Gregor was a scared 6-year-old boy in need of protection. But Ryker had to walk away. The boy wasn’t the mission.

Twenty years on Ryker is approached by two strangers in Antibes, France, asking for his help in finding Gregor – now going by the name of Gregor Rebrov. With a back catalogue of ‘crimes against the Russian state’, Gregor has escaped from a gulag in Siberia and is now in the wind.

Fuelled by old demons and painful memories of his own brutal actions in the past, Ryker finds himself once again in the thick of a complicated race against time and who knows how many of the world’s secret services, to find Gregor and get some answers.

As answers turn into more questions, they lead Ryker closer to home… and he can’t shake the feeling that he may be to blame.

A brand new high-stakes thriller. Perfect for fans of Lee Child and Robert Ludlum.

The Enemy Within
by Rob Sinclair
Release date: Feb 15, 2025

An electrifying thriller where the past never stays buried.

Some books grip you from the first page and refuse to let go—The Enemy Within is one of them. Rob Sinclair delivers a high-octane espionage thriller filled with danger, deception, and a relentless chase across the globe. Fans of tightly woven plots and morally complex heroes will find themselves completely immersed in James Ryker’s world, where trust is scarce and old ghosts refuse to stay buried.

James Ryker, a former intelligence agent with a past he’d rather forget, is thrust back into action when two mysterious figures track him down in Antibes, France. Their request? Find Gregor Rebrov, a fugitive with a history of defying the Russian state. But Ryker knows Gregor by a different name—Gregor Minko, the scared six-year-old boy he once had to abandon for the sake of a mission. The weight of that decision still lingers, and now, two decades later, Ryker is forced to confront the consequences.

What follows is a relentless, pulse-pounding journey that takes Ryker across dangerous landscapes and into the crosshairs of powerful enemies. As he pieces together Gregor’s tangled past, Ryker finds himself questioning everything—his choices, his loyalties, and whether he himself might be to blame for the chaos unfolding around him. The deeper he digs, the more sinister the truth becomes, leading him right back to a place he never expected: home.

Sinclair’s writing is razor-sharp, balancing intricate spy craft with raw, emotional depth. Ryker is a protagonist who feels real—hardened by experience yet haunted by regret. The tension is unrelenting, with each revelation hitting like a well-placed punch, keeping the reader constantly on edge. The novel’s pacing is masterfully executed, with short, gripping chapters that make it nearly impossible to stop reading.

For fans of espionage thrillers with a human touch, The Enemy Within delivers everything you could want—action, intrigue, and a deeply personal story of redemption. Sinclair doesn’t just tell a spy story; he makes you feel the weight of every decision, every loss, and every betrayal. If you’re looking for a gripping read that will keep you hooked until the very last page, this one is a must.
