I don’t even remember how old I was when I read it. I’m thinking in the late 60’s or early 70’s. It was a paperback. A young boy nicknamed Metiek (I think) gets separated from his family during the Holocaust. I think, not completely sure, it was Warsaw Poland. He gets captured and thrown on a train to one of the concentration camps. He escapes the train and ends up back in Warsaw (?) on the streets and becomes very street wise. Later he is able to make it to New York City where some relatives are located, and ends up working in the garment district. He becomes successful, marries, she is an actress. They build a nice home, she goes on a vegetarian diet in order to get pregnant, is successful and they have several kids. They (wife and kids) die in a house fire. Metiek (don’t remember his real name) is alone. True Story, his biography. It had pictures in it.
