John Lyle is a lovable innocent character. To me it is a great study in religion and what can happen if you don't have separation of Church and State. IF THIS GOES ON The book starts with this 6 and a half hour novella. Too Much Piety is More Harmful Then Too Little I recommend both this book and Heinlein's works in general to you. I had not reread this book in a number of years, and as I was listening to it, I realized how much Heinlein's ideas (which I first encountered as a teenager) have shaped my entire life. However, Heinlein's ideas and philosophy seem to me to be still quite relevant. These stories were written in 19, so in some ways they are dated. The third story deals with the building of a space station halfway between Earth and Mars. Let's hear it for separation of church and state! The second story, 'Coventry,' is about a different way of handling lawbreakers in the future. Think of Medieval Europe as controlled by the corrupt Catholic church and then add in modern snooping and surveillance techniques and wait for your blood to curdle. The first story in this book, 'If This Goes On' takes place in a future America which is under the rule of a theocracy headed by a corrupt prophet. The third is this book, 'Revolt in 2100.' It contains a novella called 'If This Goes On' and two short stories: 'Coventry' and 'Misfit.' It is not necessary to read the stories in order to enjoy them. 'The Green Hills of Earth' is next and it is my favorite of the three. The first is 'The Man Who Sold the Moon.' It is not yet available from Audible. There are three book-length collections of his future history short stories. Many of his short stories and some of his novels fit into this future history.

Robert A Heinlein had a long and extensive future history mapped out in his mind.
