The Sigma Force may be spread across the entire planet but they still manage to save the day.  Very intriguing story, lots of action and always makes you wonder "how are they going to get out of this one?".  I thoroughly enjoyed this book.

Rollins continues to impress. The sigma series has introduced me to him and I will continue to read his books well after this series.

An satisfying continuation of TFS Ingenuity.  The series is shaping up to be an exciting space opera.  Well worth a read for any science fiction fan.

Another Great Rollins Saga about the Sigma Force team. I especially enjoyed the team moving from continent to continent with great descriptive narratives of the land and its unique characteristics.

The story keeps getting better and better. Some unexpected twists for a book of this genre, but they are very well thought out and serve to enhance the plot-line in new and interesting ways. It feels like the first books laid the groundwork perfectly for future developments. Characters grow and are affected by the events in the universe in a credible way. As a fan of science fiction, I will be expecting the next novel with great interest.

Another continuation of the Omega Force crew getting into more trouble.  The whole story line of Crusher as the Lord Archon was a great one.  I loved how developed the whole race of geltans was portrayed.  It was a great read and kept me coming back for more.  Can't wait to read the next installment.

I've been reading the whole series of Sigma Force Novels, since reading Sandstorm.  Wonderful series, great characters, lots of twists and turns in the plot.  Just plain great reading

This was the first book I had read from James Rollins. I had read the reviews for Blood Line and of course his other novels popped up. So, I decided to start from here and work my way to Blood Line. I look forward to reading more from the Sigma Force series!

Volume 10 directly continues a story arc begun in volume 9 as well as heavily building off of developments throughout the series. This is not the place to start reading.

They say no battle plan survives first contact with the enemy. The Battle of the North (parts 3-7) picks up as three awakened ones, acting as advanced scouts, attack the gathered Claymores as Miria was trying to get them ready for future battle. The fights are both gruesome and very interesting, as the Claymores learn (with varying degrees of success) to deal with threats far beyond what they're used to. With the absence of the top 5 numbers the realization that the gathered Claymores might simply be a delaying tactic for the Organization hangs heavy over many. Some compelling new characters are developing here, and Deneve's ongoing conflict with her team leader Undine is particularly great. We also see a bit from the leader of the opposing forces, with a lot of intriguing implications for future plotlines.

The Assault on Pieta (part 1) sees Isley's forces attack in full. They are lead by Rigaldo the Lion, a creature both far more powerful and far smarter than any most of Miria's warriors have faced before. This chapter is brutal and open this arc with a bang.

This volume is very action heavy and still manages fantastic plot development and character growth. Easily one of my favorites so far.

I've never been disappointed with any of  James Rollins books.
If your a new reader of his  I do recommend reading the Sigma Force novels in order. I initially read the books as they were available in the library, But I enjoyed going back and rereading the series in order.

The plot is kind of outer space, but the reading was great. I found it to be most likely the best Sigma force novel (so far).

James Rollins, " the Last  Oracle"  and "The Doomsday Key"are continuing sagas of the SigmaForce
Undercover Branch of super secret service of government agency that defends our world. James Rollins has never failed to present us with two thrilling packed tales packed with with enough facts combined with believable fiction to give us two action pasted tales of super packed tales of blood chilling adventure and world life threatening events to keep one on ones toes through out the both books. I enjoyed the fact that each book was a complete tale in itself with repeating characters that one grew to know in each segment. In other words a stad a lone tale but with the same characters. I have chosen to read ten of his books. Each were just as satisfying as the next.

I have been a fan of James Rollins for about four years now, and since around 2012, I have read all of his books in the Sigma Force series. His books are always wonderful, page-turning distractions, especially in the summer. Each one is creative and insightful, with lots of action, interesting characters, and a bit of history and science thrown in.

His newest, a collaboration with author Grant Blackwood - though very much written in the typical Rollins style - is advertised in part as a Sigma Force novel. It's really a spin-off, featuring the great duo of Captain Tucker Wayne, formerly with U.S. Army Rangers, and his dog, Kane. They were introduced in the Sigma Force novel, "Bloodline," one of my favorites, and I am thrilled that they have now been given their own series. In a world of fairly generic action/adventure novels, this combination is really unique and engaging to follow. As with "Bloodline," portions of the novel are told through the perspective of the dog, Kane, and in this follow-up, they are really fleshed out as genuine characters.

"The Kill Switch," the start of this new Tucker/Kane series is typical Rollins, in a good way. It is exactly what you expect if you are familiar with his work, with a historical mystery, modern science, stealthy assassins, a high body count, and more than a few explosions. As usual, the world is in danger, and as usual, there's a megalomaniac villain at the center of the story. If you are new to James Rollins, this is actual a great introductory book. While Sigma Force is involved to a very small degree, this is clearly the launch of a new series and no prior knowledge is really necessary to enjoy. You could easily pick this one up and then dip into the lengthy and ongoing Sigma Force series if you are intrigued (and I suspect that you would be). As for me, I'll eagerly await the next in this series and all of the other books Rollins writes. As prolific modern authors go, James Rollins still ranks as one of my favorites. Recommended.

A fast-paced action-packed galactic shoot'em up in the MWM tradition. New bad guys and a whole new role to explore.  Loved the touch of romance. Keep them coming.

I have to admit, I look forward to each new book like a kid at Christmas. Eye of God was no exception. I greatly enjoyed the introduction of the newest member of Sigma, and imagine the passing of the torch may be coming for some characters...we'll see.  But like all sigma stories, it was the science, and history weaved so perfectly with action and story that drew me in and made it impossible to put down. Mr. Rollins has made me last for work quite a few times over the years. Anyone looking for an action packed shoot-em-up and get the bad guy/save the world while romancing the hot smart chick movie in book form should read this series.

Once again Myke Cole produces another fantastic book. Even though it's his forth book, it's the lead to his first series. It gives quite a bit of insight to his first 3 books. Myke writes what is now termed " Military Science Fiction." I think he writes fantastic books. Like the previous books, Gimini Cell flows smoothly from point A to the finish. Can not wait to see what comes next from this great author.

Another chapter in the life if the Black Legion.  In a future where man kind has spread out over many stars a group of 10,000 mercenaries are fighting their way back home.  Warding off the diversions and attackers of the Median Empire the heros overcome one fantastic futuristic obstacle after another.  Michal Thomas has a great series here.  Well worth every dime spent to read more.  Keep up the good work.
