"The Ringworld Throne"
I enjoyed this book and give it good reviews. However it seems to jump around. Still overall I would recommend it.
"The Moon Is a Harsh Mistress"
I've never read the print edition.
I have not.
The Moon Is a Harsh Mistress
"Starship troopers"
I was recommended this book by a friend a few years back. I will have to say that if you compare the movie to the book you will be disappointed in the movie.
