Robert Anson Heinlein (1907–1988) - “Grand Master” of American and world science fiction, multiple winner of the Hugo and Nebula awards, who secured a place in the SF Hall of Fame during his lifetime, one of the greatest authors of the 20th century who largely determined the face of modern science fiction. His works have been filmed and translated into many languages, his uncontrollable imagination still amazes new generations of readers.

He was betrayed. Betrayed by those whom he considered a friend and beloved woman. His brilliant inventions are in the wrong hands, and he himself woke up from hypothermia thirty years after anything could have been changed. Both hatred and love remained deep in the past. But those who did not give up sometimes find the “Door to Summer.” Even if it means going back thirty years.
