Whether it is the simplicity of a lively tale, the complexity of the situation, or the depth of characterization, the book has developed a loyal following. It also won Heinlein his first Hugo.

The story revolves around Lawrence Smith-also known as "Lorenzo the Great"-a down-and-out actor wasting the remainder of his life in bars.

When he encounters a space-pilot who offers him a drink, before he knows what is going on, he is on Mars involved in a deep conspiracy with global consequences. He is given a mission where failure would not only mean his own death, it would almost certainly mean an all-out planetary war.

"Heinlein's novels of the 1940s and 50s shaped every single science fiction writer of my generation and everyone currently writing science fiction. Or making science fiction movies ... and Double Star is an excellent example of all the reasons why."-Connie Will
