Sawyer is currently my preferred SF writer. This book, as for the others by him, is full of material that let the reader think about. It is not just an entretainment reading, but is indeed something more with morale, etics and so on.
Very good and recommeded to all reader, SF and non.
Reads more like an outline than a story. The concept is interesting, but the implementation is poor.
This was a thought-provoking book about youth and age, ethics and alien contact. I liked the conversations Sarah and Don had about the Draconis aliens.
