"In 1961, overnight a concrete border went up, dividing the city of Berlin into two parts - East and West. The story of the Berlin Wall holds up a mirror to post-WWII politics and the Cold War Era when the United States and the USSR were enemies, always on the verge of war. Author Nico Medina explains the spy-vs-spy politics of the time as well as what has happened since the removal of one of the most divisive landmarks in modern history."--
