This was an interesting book, set in a post apocalyptic future of underground isolated cities. I really liked the build up of information. There seems to be more from the same author so I’ll have to figure out the ordering and keep the story going. I don’t know if I’ll be doing it right now. The other stories in the series seem to be of different times, not story continuations. I’m more interested in the after than the before, so Dust will probably be the next I go for in this series.
