Valkyrie

An International Covert Ops Thriller of Nuclear Terror

By: Mark O'Neill

Narrated by: Virtual Voice

One bomb. One shadow network. One woman to stop it

When Major Sophie Decker and her black-ops unit Department 89 assassinate a Colombian cartel boss, they uncover explosive intel: a paramilitary syndicate is smuggling a nuclear weapon into Europe. The target? A high-profile political figure. The outcome? Global chaos and regime collapse.

With the clock ticking, Decker’s team races from South America’s jungles to Europe’s power centres, cutting through webs of cartel money, mercenary armies, and political betrayal. Every lead uncovers new alliances — and every move risks triggering a nuclear strike.

In the shadows of espionage, one mistake means annihilation. And if Department 89 fails, the next world war begins.

Perfect for fans of Mark Dawson, Jason Matthews, and Homeland — Valkyrie is a relentless espionage thriller of cartels, covert warfare, and nuclear terror.
