Now I like Charles Stross quite a lot, and I bought this book with high expectations. Sorry to say, the book did not live up to my expectations.
In case you haven't read the plot description on amazon, here's a (very) brief rundown on the book: Human life has gone extinct, and the androids humans built to make their own lives easier have taken over every (yes, every) aspect of human life. The protagonist, a sex-bot who has become obsolete right after she was manufactured, is on a trip through the solar system to escape the revenge of an aristocratic android she offended.
The good news first: I found "Saturn's Children" to be a very funny book. I laughed out loud a lot during the read. And it is also, as the cover and the reviews suggest, quite sexy. Now who doesn't like some sexed up writing? I certainly do. So, if you want a quick and entertaining read, this may be a good book for you.
On the other hand: The book, its plot and characters, just fail to convince me. Making androids behave just like humans would seems unimaginative. The robots just copy human behavior, they eat, they bleed, they even weep, and yes, they have desires, petty and noble. I just don't see what differentiates them from humans. That seems neither plausible nor necessary. There would have been so many fun abilities and disabilities Stross could have assigned his robot characters. There have been many Science Fiction writers (and Stross is one of them, in other books) who have explored the possibilities of artificial intelligence. Stross uses very little of those possibilities here. My feeling is that this had been a better book if Stross had dropped the robot angle completely and written a story about humans.
I tend to expect a lot from science fiction in terms of visions about the future. If you're like me and want profound speculation, I cannot recommend this book. If you want to read a sex & crime novel, which is incidentally set in future and takes place in a robot society, by all means give "Saturn's Children" a try!
