Full of mind-stretching ideas as are many of Wilson's novels, this story centers on Zoe -- a girl engineered to survive an inimical environment. I grew to care for Zoe and her fate, even though this felt like one of Wilson's lesser books. Still, that makes it better than most other author's efforts. Recommended.
I've read a few Robert Charles Wilson books. I like his style and how he inevitably drops a bomb at the end of the story that only a completely insane reader could see coming - Darwinia and Mysterium come to mind. Bios does not fulfill that sort of expectation, but it is still worth the read. If you have enjoyed other RCW novels, this one will likely satisfy you as well.
