After a gut wrenching start to the book, Rollins delivers another fast paced Sigma Force thriller. In this one a young woman creates the next evolution in A.I. But a group called the Crucible is determined to do anything to get the device and send the world back to the Dark Ages. Monk and Gray must do whatever it takes to keep the device safe.

This was intense. It felt like the stakes were raised and the characters even more in danger. Maybe it was just because A.I. will become a real concern in
My romance with globe trotting action-adventure/spy thrillers started almost a decade ago and I’ve always had so much fun reading them. But I did feel that some of them have been losing their mojo when some of their books in the past few years didn’t feel upto the mark. However, I have been pleasantly surprised in the past few months and I’m so thankful for it. While Steve Berry’s latest The Malta Exchange and Matthew Reilly’s Three Secret Cities thoroughly impressed me, this book showed me ...more

Commander Gray Pierce arrives home on Christmas Eve, only to find out that Seichan, his pregnant lover is gone and his best friend's wife Kat is on the brink of death. Kat is the only one that saw the attack, but how to get someone in a semi-comatose state to speak? A neurologist may have the answer to that. Meanwhile, a terrified young woman witnesses a massacre by a video link and realizes that her invention is the reason for this and now she has to run. These two events will link together and ...more
I will admit, I am rubbish when it comes to understanding the workings of the computer. I do know how to turn them on an off, do the important things like write my blog and compile my shopping lists, but the rest leaves me with a blank look upon my face and the feeling that somehow I have been left behind. So, in James Rollins newest outing with the brave and intrepid members of Sigma Force, Crucible, left me lagging in netherspace or is it etherspace?

At the heart of this installment of the Sigma Force series is a scary scenario: that artificial intelligence will eventually develop to an extent to protect itself against its human creators. Eve is invented by a Spanish scientist (Mara), and during her introduction to her sponsors, they are slaughtered by an ancient religious cult of witch-hunters, who want Eve to promote their agenda. Eve's last transmission is a Sigma sign. Meanwhile, the Sigma family is attacked: one left for dead and three ...more

James Rollins’ (The Demon Crown, 2017, etc.) 14th Sigma Force novel delivers such a shocking conclusion that the author actually starts off with a warning to readers to proceed at their own risk.

What starts as a lighthearted opening set in Silver Spring, Maryland, soon morphs into something tragic. Commander Grayson Pierce and Monk, his best friend and colleague, talk over drinks at a small tavern on Christmas Eve. Monk, who was recently fitted with a newer, more advanced prosthetic, uses DARPA’

Not even close to his best

I automatically order every Rollins novel to be delivered to my Kindle upon publication. One more of this caliber and I will require a sample first. While the premise was intriguing, the excess repetition rapidly became boring and the conclusion obvious. I understand the convention he was using in the development of Eve's intelligence, but a couple of examples would have sufficed.

Oh well, an occasional disappointment is inevitable. This is the first of his novels not t

The Sigma series can always be counted on to deliver a great read and this addition to the series is no exception. In this fourteenth installment, the whole gang is back for Christmas but things go bad quickly and—in classic Rollins fashion—they split up to figure things out. Though its format is similar to the previous books in the series, there's a lot about this book that feels new. Maybe it's just that these characters I've been reading about for over a decade have families and are

Sigma force? Sigma farce actually. If you are about to read this, thinking that it is another fantastic action packed Rollins jaunt involving our favourite greek lettered heroes, please don't. Stay back, retreat, theres nothing to read here!
Where to start, firstly this is not a novel, the book is comprised of an essay on neurological engineering into artificial intelligence with a very short story strapped on the back, Im struggling to keep my anger out of this review but honestly im fuming, wh

To be honest, I'm a James Rollins fan but I found it difficult getting through the book. It wasn't as enjoyable as many of his other books. I felt like he was throwing a whole lot at a wall and hoping something would stick. The whole idea of AI as the cause of man's destruction was done (equally poorly) by Dan Brown in his most recent book. I didn't love this book.

An absolute home run. Rollins never fails to disappoint, but this Sigma adventure was a real treat. The technological aspects of this novel were pivotal to its success and the detail captured was comprehensive without being overdone. Something not easily achieved. Writers hoping to deliver an exceptional techno-thriller tend to either overindulge in the tech aspects of the tale, or skimp to the point where they lose credibility. Rollins continues to walk this delicate line with precision and fin ...more
This time it's personal for the Sigma team and that certainly adds tension and upset, for our heroes and for the reader. AI is the big threat here and, as usual, we have the excellent mingling of science and action. Fascinating depiction of a developing AI, really enjoyed that. This isn't my favourite of the series (it has tough competition and I found Crucible rather over long and not quite as exciting as normal) but it's clever and it's so good to spend time with the Sigma team again and, as a ...more

Crucible is everything that you would expect from a Sigma Force novel, plenty of death defying action, cool technology, and truly evil villains, but this particular addition to the series is a bit different. Witches, artificial intelligence, and a group of religious zealots whose history dates back to the days of the Spanish Inquisition makes up the primary focus of the story but the underlining tone is really about family.

Over the years the Sigma Force team members have gone on high risk assign

Crucible is the latest Sigma Force novel from James Rollins. “Four women are killed on the Winter Solstice by an ancient order left from the Spanish Inquisition. A young scientist flees but leaves her fragile AI creation behind. Monk’s children are kidnapped along with a pregnant Seichan. Now Sigma Force must race to save their own and stop a damaged AI from more destruction.”
A wild ride from Rollins. Book has an old-school Crichton feel about the dangers of advanced technology. Rollins has done

Another fast paced thriller, this one with an almost what-if? scenario involving the creation of an AI program. The result is truly terrifying, especially because this can be become a very real problem in the near future. I hope that whoever out there is working towards achieving AI, will truly consider the consequences.

A fun and exciting read. 4 stars

"No one expects the Spanish Inquisition. Especially when there’s AI involved in the brouhaha. Another mindless entertainment to fill time better spent with Monty Python—or Indiana Jones."

"Rollins does a good job keeping the action moving, but the future scientific developments he presents fall short of the standards set by Michael Crichton."

Happy Thanksgiving friends!

I took full advantage of my break and got to tear through this amazing book! The Crucible is the 13th installment in this amazing series. James Rollins once again proves he has what it takes to keep you on the edge of your seat!

It starts with a heartbreaking beginning and doesn't let up from there. The world is on the precipice of the next technological breakthrough and due to our naitivity and carelessness it spells out certain doom that could plunge us back into the

I came upon Rollins' novels by accident and I am glad I did. I find his novels to be a good combination of cutting edge scientific research and intense suspense. This novel fits that description well. The cutting edge science is artificial intelligence. The suspense is nearly continuous as the world as we know it might be destroyed.

Another aspect of Rollins' novels I like is that it includes Christian overtones. The AI being created is named Eve. There is the theme of a created being being intro

Crucible by James Rollins is a very highly recommended action/adventure thriller and the latest addition to the Sigma Force Series. Rollins never lets you down!

On Christmas Eve Sigma Force commander Gray Pierce and his best friend, Monk Kokkalis, return to Monk’s house in Silver Spring, Md., where they discover the house has been broken into and is a wreck. Monk’s wife, Kat, is lying unconscious on the kitchen floor. Even more alarming is that Monk's two daughters, six-year-old Penny and five-ye

Thank you James, your books never disappoint! Let’s also not forget my favourite features - historical notes & science fact or fiction, makes it even better.

I could not WAIT to get this novel in my greedy little hands!! Fast paced from start to finish with more fact than fiction woven into the pages.

Interesting to note that the US announced the need to find additional funding for AI while I was reading yesterday.

Coincidence? I think not.

Rollins takes the real and turns it into fantasy. This is why I love to read his books. His imagination is again put to the test with AI facts and fiction. We know that Artificial Intelligence is already here, but where it will go in the future is part of what Rollins proclaims in this book. The Sigma Force is again put up against ancient medieval powers and witches. Who will win?

If you haven't already started reading the Sigma Force series from book 1 I highly recommend this series. James Rollins's is one of my favorite authors and if you love action-packed, thought-provoking and addictive books you will love this series!

I swear my favorite authors are conspiring to give me heart attacks reading their latest books. First Matthew Reilly's The Three Secret Cities left me wanting to cry and then this one had me in agony for a good part of the book. Every time I think Rolli

“Uncertainty is a key aspect of human reasoning. Without uncertainty, we would never doubt ourselves or our decisions. We would be certain that we’re right all the time. It’s this certainty that can make an AI’s ability to learn turn brittle over time. But if an AI is uncertain and capable of doubt, it can begin to judge itself, to question whether an action or decision will have the consequence it desires and test it more thoroughly.” 0 likes
