I realized something when reading this book, something that should have hit me long before now: James Rollins writes awesome female characters. And if you read thrillers as much as I do, you know what a rarity that is. They're smart and competent, compassionate and driven. Yet they're not cookie cutter-similar, either. Seichan's my favorite, but Jenna's a great addition to the team. It's great to open one of Rollins' books and know that if a woman ends up in a dangerous situation, she'll do her ...more

The 6th Extinction is book 10 in the Sigma series and you don't need to have read the previous books in the series to enjoy this book. Although it wouldn't hurt to read them in the right order. Mostly because the series is good and it's interesting to follow the character lives throughout the books.

This book starts with the destruction of a remote military research station that not only kills every single scientist in the facility, but also every living thing within fifty square miles. Animals,

In this 10th book in the Sigma Force series two civilian scientists - one in California and one in Brazil - are trying to develop 'outside-the-box' solutions to counteract humankind's destruction of the Earth. Unfortunately the cures are worse than the disease. The book can be read as a standalone.

FYI: Sigma Force is a secret division of the U.S. Department of Defense, composed of former Special Forces officers who've been trained in various scientific disciplines.

This is the 10th book in the series but I can't see any reason it isn't a stand alone. This book should come with a five point restraint since once the actions starts it never stops and you just careen from one dangerous situation until the next. And the story is like the Stand meets Jurassic Park if written by Tom Clancy.

The book starts off with a nice park ranger and her dog are overseeing a school trip to a lake outside of Bodie, CA. in a weird bit of coincidence I had

The 6th Extinction by James Rollins is the very highly recommended 10th Sigma Force Novel, but more importantly, it is a terrific thriller that will deliver an action packed ride to the suspenseful end. This is not a leisurely read. It is a "stuck overnight at the airport book," meaning The 6th Extinction will keep you up, awake, and entertained with minimum trips to find coffee or a distraction. In fact, you will be a toe-tapping, nail-biting mess trying to read fast enough to find what will ha ...more

Jul 21, 2014 rated it it was amazing review: If you're a fan of science-themed or techno-thrillers but you don't know author James Rollins and the Sigma Force series, it's past time to join the party.

Rollins is easily one of the top three writers of science-themed action thrillers working today. The phrase "the next Michael Crichton" has been horribly overused, but Rollins has a legitimate claim to the title. The Sixth Extinction, his newest Sigma novel, is a masterpiece of imaginative, suspenseful storytelling

It’s Alright.
Have been a fan of James Rollins since reading one of his first books Map of Bones. In The 6th Extinction, once again, there is only a matter of hours to save the world. The book jumps around quite a bit and near the end I started skimming and even skipping. Eventually got tired reading about all the killer monsters, what they looked like, what they did, etc. etc. However, for a first time reader of this author it should prove to be an entertaining read. But after reading many of hi

This is the 10th Sigma Force novel by James Rollins. All the members of the team are back, including Commander Grey Pierce, Dr. Lisa Cummings, Painter Crowe, and Kowalski. Two other main characters Jenna Beck and Jason Carter play prominent roles.

As he does with all his novels, Rollins weaves his fiction with threads of actual science and history. What makes his work interesting is the possibility that some or all of the cataclysmic events depicted could come true. This formula along with fast p

I felt like this book was a bit lacking in originality and shared many of the same info as James Rollins' other books. A few examples: this book has the underworld of Antarctica component of Subterranean, the throwback animals of Alter of Eden, the deadly virus component of The Judas Strain, and the scary flora and fauna of the Amazon like in Amazonia. If one were to mix up all those ideas into one book, it would be The Sixth Extinction. That said, it was a fairly good read, if slightly more bor ...more

I’ve been a fan of James Rollins for a number of years now, and yet I can’t help but feel that his series of Sigma Force novels are getting a little long in the tooth.

His tenth iteration, The 6th Extinction, carries with it a whiff of ‘been there, done that’ malaise and the typical Rollins formula has been reduced to a simple template. If you’ve read the series thus far, you know exactly what you’re getting. Frankly, that’s a shame. There’s no surprises, to the point that you can predict exactly

Fasten your belt, pull down the roll bar and hang on! The 6th Extinction by James Rollins starts fast and then picks up speed, twisting and turning on a dime as it takes you on a ride into the science of biogenetics and the reality of mass extinction looming above us all. Rollins does not let up in this novel, the 10th in the Sigma Force adventure series.

Rollins, what were you thinking? What might have been a rip-roaring excellent novel that transports you to a phantasmagorical world of alternate life engineered by mad scientists landed flat like a genetically mutated fish. Rollins reworks his storyline and characters from Subterranean, adds far to0 many groups of characters, profoundly confusing the reader with a choppy story line lacking cohesion.

I love the authors mix of science, history, thriller, and I would call a little sci-fi. To hear at the end of the book that many of the issues that were covered are true today. That blew me away. The possibility of doing bio-hacking in your home, or make shift lab is hard to believe. There is a machine out there that a novice could use to splice genes is scary.

Great story!!! Loved every minute of it and can't wait for the next Sigma Novel.

This book was pretty good. Good enough for five stars.

The plot was great. Great writing. I nerded out on science fiction. I liked the characters.

The action never let up. The pacing could have been better. It feels like I could barely catch my breath while reading this.

The Sixth Extinction by James Rollins

Beginning with the cursed continent of Antarctica, this story unfolds with tales of demons that haunt its dark depths and ready to eat the hearts of the living. When an emergency 911 call is made from a military research site financed by the U.S. Developmental Test Command, an unbridled discovery is made. With the involvement of Dugway Proving Grounds, a nuclear, chemical, and biological test facility, rumors of extraterrestrial research run rapid among other

This was a very weak entry in the series, missing most of what made the earlier books a notch up from the standard conspiracy-thriller fare. Granted, even at their best, they're still just trashy fun, firmly in Michael Crichton-meets-Dan Brown territory, but they're still usually fun. This one wasn't. The plot was much too simplistic, whilst also straying too far beyond even the normal levels of suspension-of-disbelief required; the villain was lifted from the Bond-movie reject pile; and the int ...more

Not bad, but Rollins js getting more and more formulaic. It felt like he was stealing bits and pieces of his stand-alones, and not doing it nearly as well as he used to write them. I felt like he missed some good opportunities with adding Jason as a character, and not having Seichan—or, really, an of the formerly significant female characters (except Lisa)—was a loss to the team. The new, guest-starring women were rather dull.

Maybe he should quit with all the crossovers from his stand-alones; it

A riproaring adventure thriller with unstoppable chills, terror, and fatality (not to.mention fatalism), THE SIXTH EXTINCTION presents a very near future of unimaginable horror. I am fond of praising the concept of Implacability in horror, but I think.the premise here beats it all out. One need only view headlines and do some research to comprehend that the consequences in this novel are far beyond Probable.

For all the "imagination" Rollins supposedly has, I would think he could do better than put random books from Conan Doyle, Crichton, Tom Clancy, Ian Fleming, Stephen King and Robin Cook into a blender and actually sell the carp that came out. This is just too much all at the same time. Genetic manipulation and lost worlds and evil geniuses and big-breasted anti-heroines and the Nazi legacy and global warming and impending extinction... all in one hodge-podge package with airhead

I have read a number of James Rollins books and this one stood out for me. It was hard to put down and I found the story very compelling. Synthetic biology, evolution machines, extremophiles, Yosemite Park, Antartica, a bioengineered ecosystem and a threat to humanity - this book has it all. A fun, exciting ride with the usual Sigma characters and a number of new players. It would make a great movie.

The 6th Extinction was the second best book I have ever read. I loved the suspense and sense of impending doom throughout the book. My favorite part was the end were cutters invention was used to help instead of hurt.


The book starts out with Charles Darwin on a ship with most of the crew and two Indians near Hellscape, Antarctica. Antarctica was covered with a lush, green forest and had a blood red, saltwater river running through it. A team in a rowboat came back to the s

Everybody is talking about the impending extinction of the human race and genetic engineering and the related science will play a big role. Dan Brown came out with his latest and now this.
As Dan Brown pointed out, I am probably in denial too. I just can't take the extrapolation of genetic sciences seriously.. Tell me the next biggest WMD is a thousand times bigger than the current one, I'll bite it. Tell me it's a modified virus or bacteria which will rip through life on ea
