Not a great book - the writing is lightweight and many situations seem unrealistically contrived (Howard Fast would've done a much better job with the same material) - but it was entertaining and, as the title suggests, is very broad in scope, covering three generations spread over Europe and the USA (basically Italy, Paris, NY and Hollywood). It also takes in major events of the period: Italian unification, WW1, the birth of Hollywood, Russian revolution, Prohibition, the Great Crash and Depression, fascism and WW2. There is triumph and tragedy and a lot of challenging decisions to be made along the way. So one is able to engage with some of the characters portrayed, though not as deeply as in books with a stronger focus. Nevertheless, it is more than just a potboiler and I enjoyed the journey enough to recommend the book.
