The Enemy Within: The action-packed, unputdownable thriller from bestseller Rob Sinclair for 2025

Pre-order 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.
