I'm a technician that does a lot of driving for his job. I use the "windshield" time to listen to audiobooks.
I really like the first Greg Mandel book, Mindstar rising. This one I just sort of liked. I'm going to read other reviews to determine if I get the third. There are way too many good books out there to read/listen to before you read/listen to this one.
The first Greg Mandel book was enjoyable. This second isn't nearly as interesting. As a mystery, it falls seriously short. It was obvious "who done it" early on, and then is was just a matter of plodding on through the book until the end. And the characters weren't nearly as interesting as in the first book. We didn't learn anything new about them at all. That's why for me it's only 3 stars.
While the first of the Greg Mandel stories was a little clunky, this book shows much of why I love Peter F. Hamilton's works. Characters are developed, plots move quickly but realistically and there's plenty to keep the reader's interest. Now I'm off to download part 3!
