The End of Eternity by Isaac Asimov

As I stated in the general Robot City review, Isaac Asimov’s introduction to this book contains some major spoilers for the novel. Especially if you are reading the entire robot series in chronological order, I suggest not reading Asimov’s introduction unless you have finished both this novel and Robots and Empire. There are many spoilers for the rest of the Robot Novel series by Asimov also. This review will most likely contain spoilers for any previous books in the Robot City series, read at your own risk.

Doctors on Earth were able to cure Ariel of her sickness, but her memory was lost. Derec has shown signs of a sickness also, but doctors have assured him it is not what Ariel had. They finally escape and eventually Derec, Ariel, Mandelbrot, and Wolruf decide to return to Robot City to attempt to find a cure for Derec.

This book concentrates mainly on answering most of the questions that were developed in the rest of the series. Robot City appears to have covered the entire surface of the planet at this point. Derec must find out what Dr. Avery has done to him with the help of his friends. Some things are left unanswered, which frustrated me a bit. This seems a bit fitting because the climax opens the door for the next series, Robots and Aliens.

This review will most likely contain spoilers for any previous books in the series, read at your own risk.

After escaping from the alien Aranimas, and subsequently the space station that rescued them, Derec and Katherine find themselves miraculously transported to Robot City. They used the Key to Perihelion, a device that somehow allowed them to travel instantly across the galaxy. I like this idea because it is twist on space travel that allows the authors to work out unique plot elements throughout the rest of the series. Derec and Katherine arrive to find themselves the only 2 suspects in the murder of a human in a city full of robots.

It seems they’ve just traded one prison for another. Since they are the only humans on the planet, according to logic the robots think that one of them must have commited the murder, because no robot could have. This book revolves around Derec and Katherine’s investigation into the murder they are accused of at the end of Odyssey. Suspicion reminds me a bit of Elijah Baley’s murder investigations in Asimov’s original Robot Novels. The style is notably different, but the murder-mystery element kept me thinking back to the originals.
