Alpine Shadows Blood & Belledonna. Alpine Shadows Nightshade Rising, #1

In the shadows of the Swiss Alps, the deadliest operations leave no trace - until they do. Mark leads a covert intelligence team with one objective: dismantle the Belladonna network, a European drug empire as ruthless as it is invisible. The mission is clean on paper. In Marseille's docklands and Zurich's quiet corridors, nothing stays clean for long. When a chance encounter pulls a civilian woman into the operation, Mark faces a problem his training didn't cover - someone who sees too much, knows too little, and is far harder to protect than to lose.
Fast-moving, atmospheric, and built on the tension of people who trust no one - including each other. Perfect for fans of spy thrillers who like their action grounded and their characters impossible to forget.
