One of Rollins Best - 5 Stars


I enjoyed this book too much to give it any less than 5 stars. It had all of the history and science elements to push my buttons. Irish history and lore, Druids, pagan and Christian history. Polar bears and the dangers of genetically modified crops all wrapped up in a nice shiny conspiracy. As usual, you have your share of explosions, near misses and enough action to keep the pulse racing.

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

This book in the Sigma series received quite a few high ratings but it didn't get it from me. For some reason, maybe it was the timing, the holidays, my brain was in a funk, I just didn't enjoy this one as much as I thought I would. The riddle, clues, and amount of factual/fictional information was too much. The wide range of information had me lost, and didn't capture my attention as much as it did other readers. I did like it, I did enjoy it, but it was slow, less methodical and took me longer ...more

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

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

This is another in the Sigma Force series, which has everything you could possibly want- action, adventure, science, history, as well as really great characters that you really care about.
Each new book I read in the series is fascinating- I learn a lot from them about a range of things(eg. in this one, topics include GM crops, Saint Malachi, the Domesday book). All written in such a way that it is informative, plot-related and extremely interesting,

“The Doomsday Key” by James Rollins, published by William Morrow.

Category – Mystery/Thriller Publication Date – 2009

I continue to read, albeit sometimes late, the books of James Rollins. I do this because his stories have a basis in history, contain actual truths, and just explodes with adventure, daring, and excitement.

What if there was a Catholic Saint, Saint Malachy, who described the last few modern Popes and that the last pope would be named Petrus Romanus and would signal the end of the wo

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

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

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

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

This was not as exciting as other Sigma Force or stand-alone novels by Rollins. Maybe I wasn’t in the right frame of mind for reading a typical action/adventure novel, because all the necessary elements of the genre were undeniably present. There was the stock villain, who: a) may or may not be played by a beautiful, mysterious, and deadly female, and b) may be working in secret or as a double agent. Next, there were the implausible chase and rescue scenes. In “The Doomsday Key”, these result in ...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

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

Well this is a nice relaxing book, easy and decent, an adventure based on some real facts that happens on real places and with plenty of symbolism and history that actually exist in real life.

There is a well constructed plot, a group of characters that will take you places with their journey and based on some historical data, there are plenty of twists and turns at every corner.

Without reveling much, so I won't spoil your fun, I would say that the main theme of the book is quite interesting, the

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.

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

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

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.

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

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.

Even though this books runs in a series, it still stands alone and I had no problem understanding or following the characters.

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
