Alex Reeve was Operative 66. A former special-ops soldier and one of the UK's most lethal weapons, he was a member of SC9 - an elite covert unit with a remit to assassinate the country's most dangerous enemies. Falsely accused of treason, Reeve was condemned to live in the shadows as the merciless killers he once trained alongside were ordered to terminate the 'rogue asset'. But tricked into revealing himself, Reeve is dragged into a deadly international conspiracy involving the British state, shadowy Russian agents... and his own father, a violent murderer newly released from prison. But if there's one man who can survive... it is Operative 66.
