As usual Sigma faces a varied and challenging task. As usual, the ending ties things up nicely. I enjoyed the entire book, but especially the very, very end. Didn’t see that coming at all. Surprised? Yes! Shocked? Maybe a little. Pleased? Enough to yell “way to go!”

As always, fantastic!!

Another heart rate accelerator from James Rollins. He’s such a great storyteller and this one didn’t disappoint.

Character development is always fun and eliminating one of the key evil characters was interesting.

Enjoyed the book you take care maybe not one of Mr. Rollins’s best. At times a little hard to follow because of all the characters.

What a ride! I agree with a fellow reviewer, I really love the combination of historical fact s, current events mingled with a great story and interesting, known and new characters. Tucker, Kane and Marco joining in the action with Sigma was a treat! Thoroughly enjoyed this latest from Rollins!

Felt like there was a ghost writer. Probably will not be in big hurry to buy the next

This story hooked me from the first page, it was hard to put down! The way Mr. Rollins entwines fact and fiction is amazing! A very good read, probably will go through it a second time to make sure I didn't miss something!

What a ride!

I always look forward to the next installment of the Sigma Force. This book did not disappoint in many ways. However, one nagging thought at the end of the story regards how much destruction the human race rages on our precious earth. It seems that no one will ever, give up an opportunity to blow things up, even if it means losing something that could benefit all mankind.
