The Doomsday Key: A Sigma Force Novel Audiobook

" I have not read anything by this author, but will try to read more. It was full suspense and historical mystery and covered biotechnology mixed with centuries-old secrets which led the characters on quite the world wide adventures. "

" Very compelling and a fast-paced read. Interesting bio-warfare plot. Really liked it! "

" a great novel by James Rollins,about a multinational company trying to control crops in purpose to control human population on earth caused some destructive microorganism resurrected back from the past "

" Awesome! Rollins is great at seamlessly integrating real life science and history with great action in his novels. With Cussler having most of his work done with co-authors now days, Rollins is quickly becoming my favorite author. "

" Josh read this book first, and he got through it pretty quick. It was interesteing, esp. given the "End of the World" in May. lol! He writes a lot like Lee Child, James Patterson, etc. Nothing heavy, just quick mystery/action reads to relax on summer days. "

" I've read a couple of his books...what I really want to do is start from the very beginning of the series. I don't mind re-reading his books, Sigma novels are my favorite - just like Ludlum's Covert One series. "

" My first James Rollins book! An action packed read. I plan on reading more. "

" This is the first time I have ever read a James Rollins book. It was a very good read blending true science and history with action and fiction. I will definitely read another one. Although it didn't make me not want to put it down still well worth reading. "

" Very exciting and suspenceful. James Rollings never disappoints. Tina you might like these books, Mom and I have been reading them. They're similar to the Divinci Code. "

" Found this book at the dollar store because it looked interesting - WOW, what a page turner! It was very suspenseful & kept me fully engaged - my main trait of a good read. Enjoyed it immensely. "

" You can keep Dan Brown. Rollins' Sigma Force is much more entertaining and interesting. "

" Fast paced, topical and just as much fun as the previous installments. A worthy successor to Michael Crichton when in comes to science-inspired thrillers. "

" definately one of his best x "

" Definitely not the worst of the series but I felt it moved through the puzzles a little sluggishly even though there was a lot of action going on. I did like that Painter got back into the field, I've always liked him. "

" no good, did not finish "

" Picked this up at the grocery store. Turns out it's part of a series. Didn't seem to affect the story much that I hadn't read any others in the series. The story was okay but I won't rush out to pick up the rest of the series... "

" Heavy reading. Have to be EXTREMELY bored to get in the mood for it. Otherwise, it's very interesting. "

" Just a great novel in a great series, loved it, and everything about it (but my memory's not so good, so I don't remember the details) But I loved it! That, I do know! "

" awesome as always...I love the action and the intelligence of these characters "

" My first Rollin's novel was a complete adrenaline ride. "

" the best book in the series so far, some really scary concepts, and a few very interesting truths. "

" It is good for what it is, a mindless, simple, quick read. If you are aware of this going in, you will enjoy this novel. Nough said. "

" I always enjoy the Sigma force books. I enjoy the way Rollins rolls in historical facts and actual locations into the story "

" I really like this series! So much action, interesting, fun! "

" Another action-packed, thrill-a-minute novel in the Sigma series. Was very well researched especially the historical aspects which added an extra layer to the story. Brilliant! "

" Need to read the earlier ones! "

" LOVED IT, LOVED IT, LOVED IT!! I CANNOT WAIT FOR THE NEXT BOOK :) "

" You should probably read Rollins' books in order of publication for more clarity. His books are wild tales with lots of action. "

" A la Dan Brown, lots of action and symbolism. It did keep me turning pages! "

" I've read a couple of his books...what I really want to do is start from the very beginning of the series. I don't mind re-reading his books, Sigma novels are my favorite - just like Ludlum's Covert One series. "

" Another good sigma force book. Exotic locations, ancient knowledge rediscoverd to save the modern world from a crisis of devistating proportions. "

" Interesting! Got some insight into genetically modified food that made me think. "

" Cerdas.Nggak terbawa arus cerita kiamat 2012. Walaupun dalam terjemahan Indonesianya malah ditambakan 2012 pada judulnya oleh penerbit lokal. Tapi secara keseluruhan bagus banget. Aksinya nyaris nggak pernah terputus. "

" I can't stop reading James Rollins. It is problematic yet thankfully only a few left to go. "

" Lots of historical facts weaved into an action story. My fav of the series. I want the honey bees back. No more GM food, please! "

" so far of reading this book at page 165, it has a pretty good storyline and im like...."WOW!" "

" This was a very thought-provoking book that had me wondering about what Rollins had said for quite a while. The scary thing is that much of what he put in his book was based on fact so maybe the world may end sometime soon. "

" I liked this book alot. The author keeps multiple story lines going at the same time hopping back and forth between the different characters story lines until they all come together in the end. I will definately read more of this authors books. "

" I love this book. He's just a great writer, and creates vivid pictures in my mind with every page. Page turning excitement, but you also get inside the heads of the characters intimately. Will get all the JR books in hardcover eventually .... great to re-read. "
