If you've read Windup Girl by the same author, imagine a similarly dystopic near future world suffering from environmental and structural collapse, largely controlled by corporate interests.
The protagonist is very much the young boy 'Nailer', I can only imagine this leads credence to the concept of this being a YA book, but honestly as someone long past young adulthood (alas) I still enjoyed this. I can't categorise it as unputdownable, but if you read Windup Girl and you are hunting for more of Paolo, this will definitely provide a fix. The style is similar, but doesn't quite have the polish, strength or the depth and breadth of character set that 'Windup Girl' has, but is still a good read.
The book begins accessibly and with quality writing instead of relying on shock value to keep you reading, and remains so throughout. Nailer feels completely a believable character, as are many of the supporting cast. At no point does the plot feel flawed or contrived, and the few deus ex machinas that are inevitable in the vast majority of fiction don't detract from the tale.
Definitely not one of those books that will stay with you, but a good read none the less, for young as well as old adults.
As ever, shame about the ridiculous e-book pricing.
