I'll say about this book, what I've said about each of the books in James Rollins "Sigma Force" series: outstanding. He has won me over, and my 19 year old daughter as well. The two of us are fans of the way in which Rollins incorporates true historical and scientific elements into his works of fiction. We also appreciate his 'separating fact from fiction' section, at the back of the book, as well as his suggestions for additional readings on his 'meaty' topics.
These books are surprisingly dev...more

Released in 2009, The Doomsday Key is the sixth Sigma Force novel, and is another intriguing, exciting, fascinating adventure. Sigma Force is a secret, blackest of the black ops organization of the United States. They investigate odd and unusual events that potentially may jeopardize the USA and world stability. In The Doomsday Key, Sigma head Painter Crowe, top agent Gray Pierce, and his team are on the trail of a conspiracy to control global population through the food supply. Seemingly unconn...more

Once again the Sigma Force goes up against the sinister organization known as The Guild.
The book opens with the destruction of an experimental farm in Africa and a massacre of all the staff and refugees in the farm. A member of the staff was the son of a US senator and the Sigma Force was given the task of investigating what happened. Monk Kokkalis, member of the Sigma Force, was about to interview the colleague of the senator's son, when a group of assasins killed the colleague and blew up his...more

As a die-hard Rollins fan, I eagerly grabbed this book within weeks of it's release. The plotline revisited some of my favorite characters, including the mysterious Seichan. I was hoping for a resolution of the Grey/Seichan romance, but I will warn any potential readers that the resolution is a bit of a grey area (drum riff).

The plotline of this entry focuses on an influential owner of a bioengineering company who has plans to "save" the world through controversial means as well as following alo...more

This my first James Rollins book and I 'read' it on audio book on a long-ish set of trips, so there was only two interruption (one lasting 18 days, the other two days). The reader/performer was Peter Jay Fernandez...who I hope does other Rollins books...and did he perform!
I enjoy history, science, historical science and, of course, scientific history, as well as action adventure (Dirk Pitt-like)and wildly expansive conspiracy plots. Here, in the "Doomsday Key" I found them all. Likeable characte...more

I wanted a globe-trotting thriller flavored with history and popular science--and I received all of the above while reading another one of James Rollins's Sigma books. This marks my fifth read in the series, as well as the first that I have read in chronological order. Speaking of: I appreciate the way that Rollins is building the Guild as an overall protagonist. Usually supergroups like Sigma don't find a worthy opponent; I get the sense that Rollins has a longterm view of the series, and that...more

I read this, and at least 4 of the other Sigma Force series books, because someone in my apartment building left them in our communal library in the building lobby, so consider this a review of the entire series. These are monstrously silly books. The plot is always outlandish, the writing is cheesy and the books are riddled with various editing errors. One of the books involves a colony of autistic savant children being raised in the shadows of Chernobyl by Russian politicians bent on using the...more
Colin
This is the fourth Sigma novel I have read, and, once again, I'm not sure exactly how I should "rate" the book.

On the one hand, there is a lot of obvious literary trickery going on--I believe Rollins keeps a deus ex machina handbook in his pocket while writing--and things that any reasonable reader knows shouldn't happen, happens.

On the other hand Rollins' books are a whole lot of fun; books that I really, really enjoy--I've read four of them, after all--and Rollins has a magnificent imaginati...more

Somewhat to my surprise I actually enjoyed this one. Normally I find the Super-secret near-superhuman solderer kind of dull, what with their improbable names, rugged good looks, quirky names or nicknames, and quit wits in a pinch; add to that this group is also suppose to be massively intelligent, trained not only as warriors excelled by no-one in history but also as scientists, researchers, and mechanics on the same level as the best in the world and I kind of expected to yawn my way through. B...more

I finished The Doomsday Key.

James Rollins is just frustrating. How can I survive until summer 2011?
This case was interesting but not the best of the author. At least I think the others were written in a more appellative way.
I have to confess I feel pretty paradoxical about this book. I really liked to know about Saint Malachai and all the things about the Popes and well it is really freaky by the way. I also loved all the things about the Celts and the Domesday Book. That was really interesti...more

more like a 3.5 -- I rounded up
My thanks to the Amazon Vine program through which I received this book.

It's really tough for me to write about books that are out of my comfort zone. I'm not a huge fan of adventure/action thriller type books, and I rarely read them. I'm much more likely to read a mystery, biography, history, work of literary fiction, or to indulge in the guilty pleasure of a horror novel or two here and there. But the fact is, there are only a few authors in the rockem-sockem wo...more

James Rollins action/adventure thriller novels are always far fetched, though the scientific details always have a basis in fact. This time, in The Doomsday Key, the scientific storyline delves into the areas of genetically modified foods, fungal viruses and super enzymes. The regular cast of characters are there, Gray, Monk, Painter, etc. with the addition of Rachel and Seichan in a new twist. I'm always very keen on the scientific elements and arcane bits of knowledge, and in this, the novel d...more

A Good Summer Read

I've only read a small number of James Rollins' books; but, from my understanding, THE DOOMSDAY KEY is exactly what fans of his will expect and love. It has an easy to read and enjoyable plot involving multiple murders, biotechnology, chemical agents, history, and lore. THE DOOMSDAY KEY is truly an adventure, taking readers from Africa to locations all over Europe, to the Arctic.

I am not familiar with the characters, but I believe they have made appearances in previous Rollins...more

I was a little late to the party with Rollins' Sigma Force series, reading the first five paperbacks in rapid fire during the summer of 2009, and as such I ended up having to wait till 2010 to get to The Doomsday Key. I could not wait for it after reading the preview at the end of the paperback edition of The Last Oracle.

To this point in the series, it's the most intriguing one yet. (The sequels are just as intriguing, if not more so.) It's all about the threat of overpopulation, and the storage...more

Car chases, crashes, bombs, and assassinations. Welcome to James Rollins newest book “Doomsday Key”. Although very action packed there lies an interesting twisting plot that makes this book a great read that kept me intrigued to the end. While the plot was very interesting it took a while to get going. The beginning of the book started out slow but slowly gained momentum and led up to a bang. James Rollins continues to impress with his fast paced action and slow mind puzzles that I enjoyed foll...more

THE DOOMSDAY KEY BY JAMES ROLLINS: Commander Guy Pierce and Sigma Force return under the prolific writing hands of bestselling author James Rollins. In The Doomsday Key, Rollins brings lots of different and seemingly individual elements together in a fast-paced adventure that will leave you reading on the edge of your seat.

Three bodies are discovered on three continents, all murdered under mysterious circumstances, and all bearing a unique Pagan symbol: a cross within a circle. Sigma Force are b...more

The Guild Plot to Starve the World. Troubling events conspire to jerk Sigma into action, as they dispatch their slugger to Rome to help a former lover Rachel combat evil that attacked her uncle at the Vatican trying to steal a mysterious relic. SEN Gorman's son's murder at an experimental UN crop station in Mali redirects Gray and company to NE England to investigate the origin of a mysterious illness that wiped out entire villages during the Druid era, with the culprit pointing to a mutant food...more

Beginning with medieval clerics taking a census for King Edward's Domesday Book and moving into real-life matters such as genetically modified crops and industrial espionage, James Rollins has created an outstanding thriller.

The book opens with the census takers and moves rapidly to what initially appear to be four unrelated murders -- except that all four victims have been branded with the same symbol on their foreheads. A friend of one victim passes an artifact on to his niece, which sets an i...more

The Doomsday Key has all the thrills, chills, and spills of your standard mass market novel pitched to males of a certain age. Yet some surprisingly well crafted passages too. There lurks the soul of a less imaginative Dan Brown or Michael Crichton here, but a better writer than the former and one to rival the latter. The Doomsday Key is in-flight reading start to finish. Adjust your expectations accordingly. (Non-spoiler alert: crazy cheesy cover may cause embarrassment on bus to work, or in li...more

James Rollins is one of my favorite authors. He not only tells a great story but he is a great writer. His way of honing in on the details brings his books alive in a unique way. The sigma force group is a band of hero's led by Gray Pierce. In this book they continue their adventures around the world as they race against time to it. In this book you will encounter mystery, loyalty, action, and love. If you've followed sigma force from previous books then the continued look into these characters...more

This book is a hot mess! Had it not been my book club pick, I would have tossed it in the donation bin by page 41 where Rollins writes that Gray wanted to bring Monk with him to Italy. He doesn't know the difference between bring and take. This is after a trundling tour bus swooped and a hospital smelled like dread (what?)The writing is terrible. Rollins' editor must have been napping. I have to give Rollins props for his success as an author when he can't write. The Doomsday Key was billed as a...more

This is the first James Rollins book I’ve read, and I must say It was a fabulous read. Even though this books runs in a series, it still stands alone and I had no problem understanding or following the characters. The way the story ended bothered me just a little, but other than that, inside the covers was a great place for my mind to inhabit a world full of spies, secret guilds, murder, intrigue, espionage, along with nonstop action. Every chapter ends by parking your imagination on the edge of...more

Listened to this as an audio book lent by a friend. It was a first experience with a James Rollins book, and was meant to provide entertainment through many, many hours on the road. It was, however, a book we listened to over a period of a few months. In that regard, it was necessary to reacquaint, with not only the story, but the characters with a bit of time in between.

Found it to be an interesting premise (although not original): good guys vs. bad guys, scientists and FBI/CIA agents, plus som...more

James Rollins has retained his great read status with Doomsday Key. His fascinating characters: Gray, Painter, Monk, Rachel, et al kept me turning the pages to see them develop and bloom throughout the pages. Rollins' impeccable research provides readers with a great understanding of history and exciting events. His descriptions of The Doomsday Book, Saint Malachy, Pagan Crosses, Crop Biogenics and even the honeybee colony collapse disorder added stimulating intellectual value to this thrilling...more

This has to be one of my all time FAVORITE books that James Rollins has ever written! I personally have gifted this book to many friends and family members! From the very beginning.. this book grabs you.. slams you back into your reading chair.. and has you hanging on to the very end. There are so many twists and turns in this book that it literally leaves you left emotionally wiped out! YES! Your mental adventure.. is about to begin! A must read for anyone who loves thrillers by a master storyt...more

4.5 stars for this one.

I really liked this book. First, because the action sequences were the most believable and plausible so far in the series. There were still some how-the-hell-did-they-do-that moments, but those were few and far in between.

I also liked the fact that Rachel is back, and Uncle Vigor as well--though he had a very, very small part in the book. I love these characters. Can't say the same for Seichan, though. Rollins is not making her likable. AT ALL. For sure she's going to be p...more
Joe Ganzi
Perhaps the previous book (The Last Oracle) was just spectacular because this one wasn't quite as gripping a tale. Excellent read nonetheless, I have grown very comfortable with Mr. Rollins' style and the Sigma characters. As always, the science facts in his books are amazing!
Jason Slovak
I won this through the Goodreads first-reads program. It sounds like it will be a fun read and I'm looking forward to it. I imagine if I like it, I'll be buying the rest of the Sigma Force series.
Deborah Gray
A fast-paced thriller with a bonus - intriguing mix of myth and history woven into the plot, much of which could be the basis for ancient British Isle legend that still persists today.

A series of high profile murders around the world become more alarming when they appear linked by an ancient symbol, and propel Sigma Force agents to uncover the truth behind not only these murders, but a more ominous threat to the world's food supply.

I enjoyed the fascinating research and the race against time a...more

Entertaining, though probably one of my least favorite Rollins books (though I've only read a few, just started his). The storyline was decent and pulled together some interesting ideas based on fact (primarily world overpopulation, decline in bee population and genetically modified foods), however, it was the fact that every chapter moved to a different piece of the storyline that made it a somewhat frustrating book to read. And note to the author: not EVERY chapter needs to be a cliffhanger. A...more
