Blood Flow is a journey set in motion by the suicide of Larry Bograd's physician father, just two weeks after Larry's bar mitzvah. In the decades that follow, Larry interviews relatives and friends of his father, Nathan, determined to understand the life and death of the man he had only known through the eyes of a child. Larry's investigation takes him behind the Iron Curtain to his father's Eastern European birthplace, and to Trieste, Italy, where his father served in the Occupation Medical Corps after World War II, only to return home a troubled man. On the trail of his father, Larry faces a life-threatening medical crisis of his own. Blood Flow travels emotional landscapes of place, time, and memory, in a quest to understand an immigrant's turbulent life and its impact on the first-generation American child he left in sudden trauma and grief. Along the way, the author discovers what matters most in his life.
