Mark Tiedemann, Mirage: The New Isaac Asimov's Robot Mystery

I am about halfway through Mark Tiedemann's Mirage and he has chosen to disregard quite a bit of the characterization that Asimov built up about the Spacers in Caves of Steel, The Naked Sun, Robots of Dawn, and Robots and Empire.

In The Naked Sun, Lije Baley travels to Solaria, a Spacer world where the inhabitants number twenty thousand and where they an almost pathological fear of human contact.

In Mirage, Tiedemann has a Solarian embassy on Earth, with the Solarian Ambassador actually meeting with an Earthman! Most Spacers didn't want to meet with humans because their immune systems were susceptible to viruses yet this is something that Tiedemann has posited here. Also in Robots and Empire, Solaria has shut itself off from the rest of the galaxy and kills all who would land on its surface, Spacer or Settler.

This is one of the things that ultimately turned me off of the novel. Had Tiedemann not used the Asimov name, I might have found this to be an enjoyable read.
