If Margaret Atwood had written this book it would have won literary prizes all over the world. Sadly, Sterling is not one of the select few authors licensed to write science fiction and have it still count as literature.
Most of all, this book is a tour de force of characterisation - we are treated to an utterly convincing hybrid between the emotional intelligence of a successful career woman with ninety years life experience and the appetite for life and experimentation of a twenty year old. But can the 'holy fire' of artistic inspiration touch such a post-human creature?
Sterling creates an utterly convincing near-future world for Mia/Maya to inhabit. The central idea is that medical science is advancing at a pace that is extending average useful lifespan by more than one year every year. The world has become a gerontocracy run by an elite, which without actually being immortal, does not die or retire. It is a safe, sane and comfortable world, but the young are marginalized and robbed of a future, being unable to compete with the experience and accumulated capital of the previous generation.
Mia Ziemann, bored, jaded and lonely, is reminded of an opportunity she lacked the courage to take in her youth. She decides to liquidate her considerable assets to buy a new and experimental treatment that promises to rejuvenate the mind as well as the body.
I am not a great fan of Sterling's work in general, but this is a masterpiece.
