I loved the setting of this novel in a future Beijing where society has become literally stratified - the poorest live in the Sixth Ring and have to pass checkpoints to even be allowed to enter the lower rings. The Sixth Ring has a strict curfew, patrolled by androids, and life is difficult. As the book opens, Ning'er has just sold her artificial arm and leg on the black market, because she has a friend who can get her a new one, and she needed cash to make rent on her small place. Her father is addicted to the drug Complacency, and takes any of her money he can access to get more. He is the one who sold her natural limbs long ago to get some cash.

So when Ning'er gets the offer of a job pulling off a heist, she can't afford to let it go. It turns out the job is from the Red Yaksha, a powerful force of resistance against the current corrupt regime. But when she learns that the person behind the Red Yaksha's mask is the Young Marshal - the son of a chief minister and an up-and-coming member of the gendarmes - Ning'er has some rethinking to do. If she takes the job, she'll have to work with a team and break into the biolabs of the corporation that produces Complacency.

So it's a heist novel with many political ramifications and bad guys who control the lives of the powerless and make those lives worse and worse. I wanted to love the book, but as the heist went down, I'll just say that some details got murky for me. I very much hope there will be a sequel, and that will make it more clear what actually happened at the end.

All the same, I am a fan of Ning'er, a scrappy girl with a prosthetic arm and leg, scratching out a living - but beginning to hope maybe that changes can be made and that the powers that be aren't invulnerable.
