A Heinlein Trio Author:Robert A Heinlein Three classic stories by the master of science fiction. Includes the Puppet Masters, Double Star, and The Door into Summer.
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.
