The Devil's Fortress
Nick Flynn and his Quartet Directorate special action team launch a daring, high-risk mission deep into Russia itself--a mission aimed at destroying the threat posed by Russian oligarch Pavel Voronin once and for all. Backed by Russia's autocratic president, Piotr Zhdanov, mercenary oligarch Pavel Voronin readies another deadly covert assault on the United States and its allies. Previously in the series, Nick Flynn and his team managed to thwart Voronin--though only at the last minute and at a high cost. Now, however, Flynn, daring pilot and agent Laura Van Horn, and the others are no longer playing defense. They're coming for Voronin--determined to take the fight directly to their dangerous foe in a high-stakes, all-or-nothing strike deep into enemy territory.
