A Heinlein Trio Author:Robert A. Heinlein Three books in one: The Puppet Masters; invasion and the results, Double Star; An Actors' finest hour(s), and The Door Into Summer; Revenge gone wrong...
In my opinion, Robert A. Heinlein wrote some of the most inventive science fiction during the 20th century. I have read and re-read most of his work over the past 50 years years and enjoyed most of it. These three stories are among my many favorites.
