Humans to become immortal cyborgs within 20 years?

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.

Derec and Ariel (previously known as Katherine) finally were able to track down the cyborg known as Jeff Leong. The Human Medical Team of robots was able to repair Jeff’s body and place his brain back inside. They let Jeff use the escape pod Mandlebrot and Wolruf landed with to fly home and send for help if possible. Until then, they are all still stuck in Robot City.

This book revolves around a robotic renaissance that has emerged in Robot City. Derec and Ariel spot a huge new building that looks more like artwork than anything else. During their investigation they find robots that wonder what it is like to be human, comedians, artists, etc. In the midst of all this a robot is murdered and Derec must find the killer and figure out why these robots acting so differently. I’d say out of the series this is one of my favorite books because it reminds me a bit of the Bicentennial Man short story by Asimov.
