The Asimov estate asked Mickey Zucker Reichert (best known for the Norse fantasy Renshai series) to write three[19] prequels for I, Robot, since she was a science fiction writer with a medical degree who had first met Asimov when she was 23, although she did not know him well.[20] She was the first female writer to be authorized to write stories based on Asimov's novels.[20]
The follow-ups to Asimov's Foundation series had been written by Gregory Benford, Greg Bear, and David Brin.[19]
Berkley Books ordered the I, Robot prequels, which included:
- I, Robot: To Protect (2011)
- I, Robot: To Obey (2013)
- I, Robot: To Preserve (2016)
