Good Sci Fi.
Two very different species have learned to live together in an underground world on an asteroid. The culture of the Avelle is interesting and complex. They have rescued the Faon and accepted them into their city. Over the centuries the Faon have adapted to the new culture and learned how to survive in it.
This fragil coexistance is threatened when intuders land on the surface of the asteroid.
The writing and describing of this alien world was so creative and interesting. The story line was filled with adventure and suspense,and how varied personal relationships were affected. The dilemas were thought provoking. The characters were very developed. I really enjoyed the book.
