Unlike that horrible Will Smith movie which shall go un-named - the true master at work... Isaac Asimov in this extremely entertaining story of humanity and our relationship with robots.
Good Science Fiction can be like gold, you can dig around everywhere trying to find it then BAM! it strikes you.
Asimov is one of the grand masters of the genre and a brilliant crafter of story and mood. His robotic character R. Daneel Olivaw is a brilliant vision of the future.
