If I was to name one flaw with the Robot City and Robots and Aliens series, it would have to be that they’re not very good. They’re lackluster, have difficult to believe plots, very simple structure, and are overall poorly thought through. Its a similar sensation to that I feel when I read the tie-in books written after Harrison’s Bill the Galactic Hero series. I feel a little sorry for the writers in later books in these series, because I suspect their hands were tied by the poor decisions of previous authors (similarly to the mess that Bear’s Foundation and Chaos had to dig that series out after Benford’s tragically terrible Foundation’s Fear).
I say all of this as an introduction to Mirage. I guess what I’m saying is that I’ve been wading through Asimov robot tie-ins from other authors for a while now, and some of them are not very good. That’s why finding Mirage was such a delight. Its well written, has a similar style as Asimov’s own writing, reuses characters and plot elements from previous tie-in books sufficiently to acknowledge their existence without getting bogged down by the poor decisions of those previous series. Its an engaging read, and I’m glad I stuck through these various series long enough to find it.
My only complaint with this book is that the epilogue is confusing and doesn’t align with my understanding of the end of the story.
