This is a great book for kids who love baseball and intrigue, like I do. Moe Berg was one of the few Jewish athletes to make it to the Majors. His baseball career spanned 19 years, from 1923 when he joined the Brookly Dodgers, to his retirement in 1942. But Moe Berg was much more than a baseball player. He was a U.S. spy during World War II and made a major contribution to helping the United States win the race against Germany to build the first atomic bomb. If you love sports and history, this is the book for you! It was great!
