What is there to say about this book. It's a classic, read it. You want more? Ok ok, Personally I think this is probably one of Heinlein's best works. It marked his change from writing for the younger market and put him well into the adult genres. Written at a time (1959) when strong conservative values were starting to be replaced with a new liberal out look on life. Heinlein draws his line in the sand and takes his stand for those old fashioned values of Honor, Duty and Responsibility. Soon after, Vietnam came along put the final nail in their coffin.
