Sigma again is up against the Guild. This time they are trying to prevent them from gaining a stranglehold on the world's food supply, and even worse control of a nasty biowarfare agent. In order to find the only antidote, Gray has to partner with his old nemisis, Seichan.
While I ultimately enjoyed the book for the same reason I enjoy all the Sigma Force novels, the fast-paced action, mystery and adventure, I'm disappointed that Rollins seems to be relying too much on certain plot devices. Most notably, the enemy unbeknownst to Gray, Painter and the rest of Sigma, managing to become part of the team. At some point you would think they would wise up. However, this does not detract from my enjoyment of the story and I highly recommend all the Sigma Force books.
