" It was a solid read for the holiday season, with adequate amount of suspense, thrill, poignance and mystery mixed with technology and "what if...." in general, and a good specimen of techno-thrillers from Preston & Child. The story involves the efforts made by a group of people (sponsored by a megalomaniac millionaire) to retrieve a mysterious piece of rock, and what happens to the gropu as well as the ..er... rock. However, after the standards set by "Relic" and "Reliquary" by the same set of authors, I was compelled to give ony 3 stars to the book in question. I hope that their subsequent efforts would be better, and closer to the standards of "Relic". "
