About this listen
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.

Story
Nathan Tyler is an unassuming professor at a middling American university with a rather obscure specialty in mathematics—in short, a nobody from nowhere. So why is the White House calling? Summoned to Washington, DC, for a top-secret briefing, Nathan discovers that he’s the key to a massive foreign intelligence breakthrough. Reading between the lines of a cryptic series of equations, he could open a door straight into the heart of the Kremlin and change the global balance of power forever.

Story
Curtis Delaney watches the footage play out on the news, and immediately recognises the unidentified hero. He hasn’t seen his brother Finn in six years. He doesn’t know where he’s been in that time, or what he’s been doing. But there’s one thing he does know: Finn is no hero. Curtis is determined to find his brother, but equally, Curtis is no detective. A husband and lawyer (and not the 'good' kind), with a mortgage and responsibilities, Curtis isn’t cut out for delving into whatever seedy business Finn has gotten involved with.

Six weeks ago, Gideon Ryker awoke from a coma in the French chateau where veterans of the Foreign Legion live out their final days in peace. His body is a torturer’s canvas, his mind an empty slate—except for haunting dreams of a young girl’s face. He doesn’t even remember his name. But he knows that a legionnaire’s life is a brutal struggle. The only reward: a new identity and passport. A fresh start. You’d only take that deal if you needed to forget your past life.

Abductions and murder are not what ex-DCI Luke Sackville expected when he left the police after tragedy struck his family. Luke’s return to the workplace was meant to be a soft landing, but when a woman vanishes after being accused of taking bribes, he is assigned a disparate team and tasked with tracking her down. Their search becomes more urgent when her disappearance is linked to the death of a second woman. When a third goes missing, the hunt becomes a race against time.
