Ex-deniable operator Nick Stone has spent a lifetime in harm's way - but when someone he cares for very deeply is murdered in cold blood, he can no longer just take the pain. A high-level internecine conflict at the dark heart of the resurgent Russian Empire and an assassin's bullet on an isolated Alpine pass propel him from an apparently run-of-the-mill close-protection task into his most brutal and challenging mission yet. As the body count increases, Stone becomes one of Europe's most wanted.
