This was a freebie on Amazon, and it turned to be the companion (read teaser) to the new book Rat Runners.
Imagine London with more cameras and observation on every street corner. Privacy has been sacrificed for the greater good of safety. Children, so-called rat runners, are observed less so they are used to do the legwork for the criminals.
Although it was quite an interesting story (not that original because it is Orwell’s nightmare in London again), it was too short to get attached to any of the characters or to really get into the story. I quite liked the writing, so if I were to come across the full novel, I think I would read it.
