A classic tale from the Grandmaster of Science Fiction.
Podkayne Fries, born and raised on Mars, has just one ambition: to earn her wings as a starship pilot and rise through the ranks to command deep-space explorations. The opportunity to travel aboard the Tricorn- on an interstellar journey to Venus and Earth in the company of her diplomat uncle-is a dream come true.
Poddy's idea of diplomacy is keeping the peace with her troublesome brother, Clark, but she's about to learn some things about war and peace. Because her uncle is the Ambassador from Mars to the Three Planets Conference, which makes him-and his niece and nephew-potential targets for any radicals looking to sabotage the negotiations between three worlds.
