Elite Ukrainian assassin Ruslan Akulov, aka Wolf Six, is a ghost. A weapon for hire forged in the fires of conflict and tempered by experience. Known by both the underworld and international intelligence agencies, he works alone, guided only by the next mission and his unwavering commitment to his personal kill code.

So when a routine contract in Argentina turns from simple to chaotic in the squeeze of a trigger, Akulov is thrown into a complex web of deceit and dangerous tests of loyalty. Akulov had heard of the French intelligence operative Sophie Racine – her reputation and skills are world-class, but when her business becomes his problem, Wolf Six must quickly learn to work with others.

Thrust into a high-stakes partnership with Racine and an old comrade he believed was dead, Wolf Six must stop a deadly conspiracy to reignite a defunct Basque terrorist movement. The ‘explosive’ trail leads from the turbulent streets of Buenos Aires, via the Colombian cartels, to the elegant boulevards of Madrid.

Akulov and his allies must stop a new wave of terror attacks before countless innocent lives are lost…

Buckle up for an explosive read you won't be able to put down! 💥
