Despite an off-putting cover that appears to have been designed with 14 year old boys in mind, Charlie Stross' "Saturn's Children" is an interesting read with a great premise -- once the human race dies off, what's to become of their androids?
In Stross' clever scenario, they continue on -- struggling to fulfill the aspirations of their extinct creators (space exploration, extraterrestrial colonies) while picking up a few of our less than noble traits too (slavery and murder to name a few).
The story centers on Freya Nakamichi-47, an obsolete pleasurebot (see book cover) who, like her identical sisters, has had to find other duties once human males ceased to exist. Most of her work has been mundane, but when she's hired to make a delivery to Mars things start to get interesting and extremely dangerous.
Hardcore intrigue, brutal assassinations, and heart-breaking betrayals easily place "Saturn's Children" in the category of a sci fi thriller (android noir, if you will) as Freya does her best to navigate through a deadly future where absolutely no one can be trusted -- even herself.
