Vehviläinen, Olli Finland in the Second World War (0333801490)
This book describes the struggle for power between two totalitarian dictatorships in the north of Europe and the battle for survival of a small nation caught between them. In the Winter War of 1939-1940 Finland successfully fought off a Soviet invasion. Then, with none to turn to but Germany, it became the only democratic state on the Axis side. Ultimately, it succeeded in extricating itself from the war and, despite the shadow of Russia looming over it, averted a Communist takeover.
