NO SPOILERS!! Another winner from Mr. Rollins. This was my 5th James Rollins novel and my 2nd Sigma Force book. Overall, his books are excellent - the writing is seamless, the story is exciting, the characters are well built and the science part of the stories is very well done. Mr. Rollins does a very nice job of blending real world events and places with advance science, weaponry and technology. This is the first Sigma novel in the series and I very much look forward to reading #2.
