This book touches on topics of racism, government, slavery and more. In true Heinlein fashion it pushes the boundaries of comfortable discourse. What would you do if you found yourself and a few family members alive after a nuclear war? What kind of organization would you come up with to govern the survivors? What would you do if your own son decided to question your authority? Would you kill him? Could you leave alive someone who wasn’t willing to follow the rules in a situation where doing so means survival or death? What would happen if you find yourself captured and at the whim of another? Would you live free or die?
Hugh Farnham was a practical, self-made man. and when he saw the clouds of nuclear war gathering, he built a bomb shelter under his house, hoping for peace and preparing for war.
