The performance of this book is very good. There are several characters and the story continuously jumps between them. The reader's voices make it e..Show More »asy to follow each scene change. The book itself is mediocre story telling and the kind of science fiction which is very easy to digest because it doesn't go well beyond current capability. The author appears to have read (from the terminology borrowed), very good Sci Fi writers such as Dan Simmons. If you are into deep sci-fi, I would skip it, but if you are up for something at the quality level of a good TV miniseries, this can be an enjoyable listen.
