WWII alternate historian Conroy (1945
) sets this tale largely in Berlin as it prepares for division among the four Allied powers in accordance with the Yalta agreements. President Truman doesn't trust Stalin and makes the controversial decision to move his troops across the Elbe River toward Berlin in an attempt to lessen Stalin's growing influence in Europe. The move ignites smoldering tensions between Russia and the States, and Stalin's enormous Red Army attacks its former allies, extending the war and threatening the world. An ensemble cast of fictional characters (an American soldier, a German refugee, a professor of Russian history turned secret agent, etc.) and historical figures powers the meticulously researched story line with diverse accounts of the horrors of war, making this an appealing read for fans of history and alternate history alike.
