This is the first of a trilogy billing itself as the second foundation trilogy based on Isaac Asimov’s Foundation Trilogy. Although a three-book set, each can stand on its own very well.
The author explores some elements left up in the air by Isaac Asimov, and fills with more current knowledge and philosophy, such as addressing why there are no non-humans in the galaxy.
Some of the topics he addresses include expanding on Dor, who she is and giving her a little background. Her character is expanded, and perhaps changed a bit, at least from what I may have imagined. In general, he adds a lot about computers and robotics that Asimov didn’t go into, or couldn’t because the technology wasn’t available. Philosophically, he approaches the topic of computer intelligence and what could constitute life. In this, Hari creates two simulated people, Voltaire and Jean of Arc, to help him understand society and to help further his psychohistory, Voltaire and Jean of Arc act as a yin and yang, who’s arguments are designed to answer questions. But they evolve their own desires and take on life beyond their programming.
I found the book difficult to work through at times, but still an interesting addition to the Asimov series. I believe those fond of the Asmiov trilogy will enjoy this and find it interesting. It adds background to the trilogy and brings it a little more into the present. Otherwise I don’t think it may not be worth the effort.
