'Duty' is a very special book. It takes three individual subjects and, through Bob Greene's rare talent, makes them not only analogous, but seemingly inseparable. I haven't been this affected by a book in 20 years. This is going to stay with me for a very long time. A father's dying days, the dropping of the atomic bomb on Hiroshima, and the mindset and value system of the twentieth century's most intrepid generation. Greene not only ties those 3 subjects together in a seamless storyline, he changes your mindset, expectations, and definition of the word "duty". Want a great war story? Listen in on the 3 principals who, in their own words, describe how they carried out the single most destructive act in the history of the world. Want a father-son love story? Read the words Greene's father recorded onto an audio tape for his son. Words, spoken years before his last, sickly, dying days, described his life. Words, sounding vibrant and hopeful, that Greene listened to even as at the same time, he could hear his father's frail, confused voice in the next room. Ever wonder what made the Depression/WWII generation tick? Read, in their own words, how they think. What is important to them--how they process and catagorize beliefs, responsibilities, and minutiae--why individual accolades and the collective spotlight is more distraction and frivolous emptiness to them than positive reinforcement. Paul Tibbets (....the man who won the war), gets the most print, but his generation as a whole is the character that drives this book. In Tibbet's own words, " Who knew who doesn't matter". What matters is duty, and a job well done. Well done, Bob Greene. Thanks. Read it. Read it for your own good.
