Move over Andy McNab and Chris Ryan, there’s a new SAS veteran writing thrillers and he’s good. Very good. Stephen Leather’s John Carr has recently left the SAS, after a long and distinguished career, and is now working for a Russian oligarch in the murky world of private security. But an incident from his past – in which three terrorists were brutally killed – suddenly comes back to haunt him. Tracked by a hitman out for revenge, John Carr is forced to stepover the line to defend himself and his family. It’s a cruel and violent world – and one he thought he’d left behind. Patriot Games meets Taken: In Once A Pilgrim, John Carr show all the Reacher-esque hallmarks of a cold-blooded anti hero doing what needs to be done, whatever the consequences. But some wars never end.
