A tale beloved by many fans of Robert A. Heinlein, Podkayne of Mars tells the story of a young Marswoman and her inter-planetary adventures with her uncle and her genius brother.

Told largely through Podkayne's diaries, the story details her travel to Earth with her two companions. Podkayne has very definite plans on what to do and how to do it, but not everything is as it seems. She is suddenly thrust into the middle of life and death situations when the liner they are travelling on makes a stop at Venus.

The original publisher of this book asked Heinlein to change the controversial ending, which Heinlein did extremely reluctantly. He felt the original ending much better suited the story line and was never satisfied with the modified 'safer ' ending. This edition restores the book to how Heinlein originally wrote it. It also includes a letter to his agent, decrying the changes asked for by his original publisher.
