Alex Reeve - known as OPERATIVE 66 - is a former special-ops soldier and one of the UK's most lethal weapons. Previously a member of SC9, an elite covert unit with a remit to assassinate the country's enemies, Reeve was framed for treason and now lives a nomadic existence - as the merciless killers he once trained alongside hunt him down.

For a chance of a normal life, Reeve must expose and dismantle the sinister SC9. So when a series of brutal killings in Germany have all the hallmarks of an SC9 tactic - the murder of 'ghost targets', decoys to camouflage the true intended victim - Reeve finally sees opportunity for revenge.

Sucked into shadowy conspiracy involving dark global powers, Reeve will risk his life to save others - and to secure his freedom. But if there's one man with the skills to do so... it is Operative 66.
