One of the best! Non stop action from beginning to end. Rollins makes you stop and ponder all the wild actual things that could happen. You won't be disappointed with this book.
Commander Gray Pierce, and Sigma, joined by a pair of Vatican historians, race to uncover a truth tied to the fall of the Roman Empire, to a mystery bound in the roots of Christianity's origins, and to a weapon hidden for centuries that holds the fate of humanity. I love the Sigma Force series but not this one. I found the book to be too convoluted and didn't understand the science that was presented in the book and I found it therefore boring. I loved that Seichen met up with her mother and did enjoy that aspect of the book. I'm just going to mark it as a one off writing for James Rollins and move onto the next book. I did give him 3 stars for writing the book.
