Very engaging Science Fiction story. The characters are richly developed, the ones you love and the ones you hate. The story has a lot of science given in terms I could understand. It then develops into the fictional science that takes us far out, but is reasonable. I loved the idea used for this and the story of the characters who come together to solve a big mystery. This is a very well-written book. As much as I loved the story and want to get the next book in the series, I am sold also on the author and enjoy so much the style of writing. Highly recommend for Sci-Fi readers unless you are looking for those space war type books.
