The German war machine is in retreat as the Russians advance. In Warsaw, Resistance fighters rise up against their Nazi occupiers, but the Germans retaliate, ruthlessly leveling the once-beautiful city. American Adam Nowak has been dropped into Poland by British intelligence as an assassin and Resistance fighter. During the Warsaw Uprising he meets Natalia, a covert operative who has lost everything?just as he has. Amid the Allied power struggle left by Germany?s defeat, Adam and Natalia join in a desperate hunt for the 1940 Soviet order authorizing the murders of 20,000 Polish army officers and civilians. If they can find the Katyn Order before the Russians do, they just might change the fate of Poland.
