First offence, erasure.  Second offense, death.  A nameless girl is dropped into an outpost where the most basic needs are almost impossible to come by.  Robots enforce the law without recourse.  How can people escape, let alone survive in such a world?

This is the first best-selling book (according to Amazon) from a self-publisher to become popular with the general public.  It will be interesting to see how the platform/publisher fares with regards to promoting their authors to the New York Times best selling list.
