Query: Otto,Boy at the window

The book takes you on a journey with a young boy named Otto. His family's trip from Vienna during the start of the Holocaust to their arrival in America. When Otto looks out the window he sees how everyone else around him live with loving parents. He finds no love in his own family except for Otto's brother Heinz Robert. Otto's success is due to hard work and long hours. This has taken him away from his own family. Eventually, the long hours at work pay off with success and family love and appreciation. A joy to read and to think about your own family's hardships and success. I am gald that my son-in-law (Joe) gave me this book to read.
