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 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

I've been a fan of Rollins' work for quite some time, especially the gripping Sigma Force series so I was pretty excited when I heard a new one was about to drop. When I read the inside of the jacket I said to myself 'this is going to be GREAT' and I wasn't disappointed!

Rollins has a lot of balls in the air with this one. Genetically modified crops, ancient history dating back to the Egyptians and encompassing the early roots of England's history, civilization, and religion...shadow organization...more

Another good action/archeology/suspense/political thriller from Mr. Rollins. I look forward to reading the next in the Sigma Force series. I know that this is pure escape fiction, but I have been very entertained by this series, and have actually learned a lot about real history from it. I am always coming across plot devices that Mr. Rollins uses and thinking "No way is THAT real..." and then I google it. And sure enough... a company in 2001 really WAS trying to market corn bio-engineered to ca...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

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

Rollins is a wildcard...,

I picked up a copy of Rollins' Map of Bones when it was first released. I was blown away; it was a great book (I gave it 5 stars). I then moved back to Sandstorm and was dumbfounded; how could that have been by the same author? It was horrible (I gave it 2 stars) and I swore off of Rollins.

But, here came a story that sounded really good, so I gave Rollins one more chance. This book is okay. That is the best I can say about it. Its not horrible and its not great; it just....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

I liked this book. I'm not a big reader of the cop/special forces/suspense/etc. genre, so I'm not sure how typical this book is, but for me, it had the adventure/quest component, the symbology, and history that I liked in Da Vinci Code, and even threw in a reference to Merlin for kicks.

A special forces team, recovering from a major set-back, split up to figure out why bad guys are killing people and branding them with a symbol known for ecological groups. There's a lot of explanation about the...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

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

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
Glee
He just keeps rolling with the page-turners. If you like Indiana Jones/DaVinci Code/Jurassic Park page turners, this is your guy. His characters are pretty weak, but actually getting better. Male-female relationships are really empty, but heroes don't have time to worry about that kind of silly stuff. Just painful when author tries to work through emotional scenes. He's an adventure story teller, whose stories have the action happening too fast and furious to slow down for introspection. And occ...more

Rollins hit all the key fears of my life. Global Warming, Over Population, Pollution, Genetic Manipulation gone wild, Honey Bees disappearing, drought, and war. All the same characters are here, Painter Crow the the rest are fighting "The Guild". With a little science and a great imagination Rollins takes us to a place where "The Guild" uses a rich Norwegian man who wants to save the world from self destruction and shows us one solution to the "Population Bomb"

I enjoyed the book. I listened to t...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

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

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
Kate Hart
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
David Ketelsen
I enjoy the way that Rollins writes but I find the entire Sigma Force versus The Guild annoying. It reminds me of the old TV show Get Smart. Having two agencies fighting each other tooth and nail yet being totally secret and unknown to the general population is fine when played for comedy, but it's difficult to take seriously.

In Doomsday Key there's multiple times when military jets and helicopters attack our intrepid heroes, and this force is projected on multiple continents and in public areas...more

Have you ever finished a book and felt like there was meant to be another chapter? Or is it that there was a chapter too many that makes you think there is more to the book? Either way, this is my second Rollins book and I have felt the same way after both. I'm unsure if this is a deliberate move by Rollins to make me want to read another of his books, or if it is just that I'm somehow unfulfilled by the end of his novels.

Guess I need to read another of his books to find out. Fortunately I have...more

I read this book in 2 days, because it was wicked hot/humid & I couldn't muster up the energy to move. If I could've done anything else, I would not have finished this novel.

This story is told from SEVEN points of view, which throws off the pacing a number of times. Just when a POV gains momentum, the chapter ends and Rollins switches over to someone else. Rollins tries to tell the story from the multiple villians' POV, but for me it just weakened the tension, rather than winding the reader...more
Jeremy Miller
This was the first Sigma book I read, and even through I read out of order, this book was amazing. Only certain parts needed filled in by reading earlier books. The mix of action/suspense with awesome science based riddles make this book a mode a modern day Indiana Jones, except better.

Rollins does a fantastic job with the plot, with the details, and keeping the suspense up. The amount of research into historical archives for each book is impressive. This is the book that made me fall in love wi...more

So, it took me a long time to read ...for personal reasons not the book itself...but I finally finished this book THANK YOU GOODREADS FIRST READS! THANK YOU JAMES ROLLINS! Firstly, I am A HUGE Fan of James Rollins...it started with Amazonia, I love the Sigma Force novels as well...This book was one wicked adventure from start to finish. I love the rollercoaster ride that James Rollins had me on. James Rollins is like Dan Brown meets Robin Cook, He weaves a masterpiece of "fact" based fiction on...more

A fun thriller ride with plot lines that resemble an effective blend Dan Brown�s archaic forces, Ludlam�s perpetual motion of enemy forces, and Crichton�s threats of pathogenic apocalypse. Three murders in Africa, Princeton University, and the Vatican, all involving branding of the bodies with a Celtic cross symbol, propel the shadowy Sigma Force intelligence team into action. And the action never stops as one disaster unfolds into another, and clues sought to the mystery. The starting clue lies...more

Il peggior libro di Rollins fra quelli che ho letto finora, e che riassumerei così: "Mentre una nuova minaccia incombe sul mondo, la Sigma è spazzata da un vento ormonale; ma tutto finirà per il meglio grazie ad incredibili gesti atletici."

Sul serio: sapere qualcosa della vita sentimentale dei protagonisti ci può stare, ma questa era una storia d'azione allungata con un Harmony. E a proposito di azione, c'è un limite all'assurdo, oltre il quale la suspance si trasforma in ridicolo. (view spoiler...more

I had forgotten about this series for a while, but when I needed a book for a plane flight, I thought I'd see if there were any more. Sure enough, this one had come out and another is about to follow. One thing I like about this series is that the books are self-contained enough that if I go a few years between books, I don't feel like I'm missing much that's important. As with any book of this ilk, there's all kinds of unbelievable characterisations, convenient epiphanies, etc. But, as I have c...more
Amanda
I think that I liked this book the best out of all of the Sigma Force novels I've read.

The history part of the book is about the early settlers in what is now England. I really like that most of the history and myths he tells you are true to life (at the end of the book he'll tell you what is true and give recomended reading).

The modern part of the book dealt with geneticaly modified crops and population overgrowth/food scarcity. And although this book is a work of fiction... it is also kind of...more
Barbara
This is a fast-paced, suspenseful novel that represents some very good research on present-day biotechnology and Neolithic English history by the author. It includes historic facts about the Celtic Cross and Neolithic England, when paganism and Christianity often bumped into one another. A Norwegian company has been investing in biotechnology research projects that the CEO feels will address the twin problems of an overpopulated planet Earth and an inadequate supply of food. The death of a U.S....more
Alicia
The Doomsday Key is the latest in the Sigma Force series, although one need not have read any of the earlier books to understand the story, as all pertinent background information on characters and their relationships is presented as they are introduced in this book. Never having read (or, admittedly, heard of) any of the earlier works in the series, I had few expectations informing my reading experience, other than having seen a few diagrams while flipping through my pre-pub copy (I'm a sucker...more
Melissa Morrow
Took me a long time to get into it. I guess I'm not as much into the Thriller genre as I used to be. There seemed to be an inordinate amount of everyone zooming around on motorcycles, snowmobiles, MINI Coopers or having discussions in luxurious jet planes. I guess that's a thriller, right? Gotta keep moving? It was tiring. But about page 320, it got a little more interesting and I was able to push through to the end.

I was afraid it was going to be a kind of a Dan Brownesque treatment of the Cath...more
