Crossing Frontiers is an autobiography. It starts with a short historical background of the author's home country, Germany, as it refers to his story. Growing up during the depression and under Hitler's National Socialists, he saw the Third Reich rise and fall. He relates interesting and humorous events from his school time, his training in the Hitler youth, labor force and military. In riveting details, he describes his war experiences, his return to his home in search of his mother. He points out the dangers he encountered living under Russian and Polish rule and later being expelled. He describes the situation in Germany after the war, illustrating it from his experience in refugee camps in East Germany, and his escape to West Germany. He compares university life in Germany, where he studied for his degree in architecture and the USA where he studied on a scholarship for a year. He narrates his adventures, hitchhiking through the United States, masterfully. His story ends with his decision to immigrate to Canada.
