If you are new to the Science Fiction genre, vintage Robert Heinlein is a great way to start. The vast majority of you might remember the movie, Starship Troopers. Amazingly, this movie was based on one of Robert Heinlein's books written in the 1950's. Have Space Suit Will Travel is every bit as well worth reading.
Totally outstanding Heinlein classic work. He is in the Science Fiction and Fantasy Hall of Fame. This is a very nice sample of his work.
1958 SciFi classic.
