First off, this is a great book. A really wonderfull book. And the best thing I can really say about it is that it got me interested in science fiction again, after a long hiatus. The book takes on a theme made popular in the golden age of science fiction; artificial inteligence. But Daniel give the subject a really great feel. He dosent make the mistake of trying to make the robot yearn for humanity. But it is a compassionate intelligence experiencing intense relationships with humans. but maybe i am over analyzing. let me leave it at this: this is a great book, even if you have never read science fiction.
