As you have probably guessed by the title this book is the story of Harry’s many lives. He serves in both world wars multiple times, he marries the same woman often, and he tries to have a relationship with both is birth father and his adoptive father. His birth mother dies when he is born and his birth mother always dies early in his life. You see Harry relives the same time period each time his life starts over. However in each life there a subtle changes which change his actions and the world around him. Take Vincent for example, he is sometimes a friend, sometimes a foe, and sometimes a companion depending on which life Harry is living. I found the idea of being able to relive your life multiple times fascinating and I often found myself feeling for Harry sometime happiness, sometimes frustration and sadness as well depending on the circumstances.
