Three missions. No oversight. Just bodies.

Germany’s enemies don’t follow the rules — and neither does Department 89, the covert military unit that doesn’t officially exist. Led by Major Sophie Decker, a woman known across Europe as judge, jury, and executioner, they strike first and vanish without a trace.

In Books 12–14 of this relentless thriller series, Decker goes head-to-head with North Korean operatives, dismantles far-right terror networks, and uncovers a plot that could ignite a war across Europe. These aren’t missions — they’re kill orders.

Three full-length spy thrillers. One ruthless heroine. Download the boxset now and enter a world where justice is delivered through the scope of a rifle.
