Chilling yet enticing story of a possible dystopian future

This book appears to use wonderful contrasts between the freedom of nature and the constraints of society. Very Romantic era. Additionally it covered the conflict between emotions and logic. The plotline so far demonstrates a very possible future. Although some of the technological terms flew over my head, the realisticness of it is very enticing. I'm interested to delve more into the relationship between the sisters, how they adapt to their environments, and how they learn to live and grow on their own.

The cover is stunning with an incredible contrast between light and dark. Perhaps it demonstrates a difference in the fate of each sister? I'm excited to read the rest of the story when it is released!
