532 pages containing 11 stories, reminding us of an era when authors were expected to make sense of the science-fiction elements they included into their stories, then create a plot around the drama created by the use or misuse of technology, rather than employ science fiction elements as magic wands that suddenly come and cancel the drama. And never forget: the idea that the story could have a very unsettling, very grim ending, and that even the happiest ending still contains shades of gray, rather than the expected happy ending of nowadays.
