The Puppet Masters can be sumed up in one word, it ROCKED!! My first Henlein book was Farnham's Freehold, which don't get me wrong wasn't a bad book but I just couldn't get into it. The Puppet Masters was, I think far better. Filled with suspense, paranoia, action and even a little terror. A basic outlining of the plot is, Earth is under attack by aliens that can control people's minds. They can attach themselves where ever they please on your body. An Intelligence officer, known as Sam Cavanaugh must stop these aliens with the help of a beautiful agent named Mary and the Intelligence's commander the Old Man. This book starts right out with tons of suspense. Even to the ending, the last five pages still had my hands sweating! If you are a Heinlein fan or just plain love Sceince Fiction read this book. I couldn't put it down!
