Blood Lines By James Rollins

The best Sigma Force Writing yet!

This is the latest in the Sigma Force series. To me, it’s likely the best one yet. I’ll tip my hat to the fact that there is a cadence to these books that allows some of the surprises to be “expected” in one way or another. That’s likely the case with many series that run longer than 5 or 6 books. That accepted, it’s the case here.

I also had some trouble wondering why, after so many books, each book having about a year between them in

I read this while I was in the goofy garage during 2014. My delightful friends supported my reading habit, and never once wondered (to me, that is, I have no idea what they said amongst themselves!) why I was asking for Rollins's books.

I wanted to read them because they are very entertaining, have enough plot and character development to keep me distracted from being in a public mental health facility, and are intensely visually told stories with deep sci-fi roots and so

Here is another wonderful book by an author who does make me always sit and read from cover to cover in a matter of days. (well hours really!) There is something about his books that always thrills me and makes me ever so eager to read and read and read.

In this current novel, we are again thrown into the sinister world inhabited by the Sigma Force agents. All the fantastic characters are back with the addition of two new ones, a man, Tucker, and his combat trained dog, Kane. (hopefully they will
My God, this was the MOST FUN I had racing through the pages of a novel in recent times! I was eagerly waiting to read the book for so long as this one was promised to be the Finale of the ongoing Sigma Vs. Guild war, and Rollins painstakingly slowly but rightfully built up that ever escalating war since the very first book of the series Sandstorm through the last seven books of the series.... and boy oh boy, did he finally deliver! He gave us all the actions and mysteries and sheer epicness fro ...more

Just finished almost an all-nighter because I simply could not put this book down. Sometimes sleep is over-rated anyway and when you find an amazing, edge of your seat, suspense thriller, you have to finish it.

In Bloodline by James Rollins, you are in for an action-packed roller coaster ride from the beginning. Trying not to give away too much, this novel blends a little DaVinci Code, National Treasure, Indiana Jones, Mission Impossible and a twisted bit of Science Fiction into this one, so if y

The series has lost its shine - 2 1/2 Stars

For many years, James Rollins has been a “go to” author for me. I always knew that if went back to his writing, I would find an enjoyable and exciting read. It has been 2 or 3 years since I read the previous novel in this series. While it is much as I remembered, I was left disappointed.


Just read the jacket cover. It’s much the same as the others.

My Take

I has always seemed that Rollins can put books out at a fast pace. For many years this has

When I buy James Rollins books, I usually do it when he visits our local bookstore, the Poisoned Pen. I buy 3-4 copies, get them signed and hand them out to friends. I think of these gifts as part of my evangelical mission on behalf of the world of thrillers. Mr. Rollins makes a great ambassador for the genre. His stories are perfect examples of thrillers, giving the reader a heavy dose of nearly believable science delivered with a boyish sense of adventure and just the right hint of humor. Fun ...more

There were two things that I absolutely loved about this 8th in the series of Sigma Force. Captain Wayne Tucker and Kane, his brilliant K-9 soldier/partner and baby William. I just love babies and doggies. Another great adventure with the Sigma clan, another shocking realization involving the Guild villains. Wow. I didn't see that one coming. The only thing I really just didn't like was the invention of the neobots or microbots or whatever the heck those scfi-fi creatures were. Reminded me of so ...more

Ok so after having devoured half of this series you'd think I'd get sick of the science+action+ass-kicking combo, but nope! Rollins knows his stuff, and he does it well.
What really, truly broke the mold on this was Tucker & Kane. I am a big animal lover and even incorporate animals in my own books. I get a lot of my inspiration from my own two dogs.
So when Rollins introduced Kane (military dog, Tucker's partner), and to top it off had scenes from the dog's POV... I was ready to frown and comme

Yes: there is a point where the bad guys kidnap one of the good guys, leaving the remaining protagonists racing to outdo the maneuvers of their evil opponents. Rollins, you did it again. In fact, I may start referring to this plot device as a "Rollins." Like, "Damn, they just pulled a Rollins! We must save her!"

In James Rollins's Bloodline, the 8th installment in this exhilerating thriller series, this novel would take you to the edge of your seat and make you drop your jaw. It all started when the president's pregnant daughter was kidnapped by Somali pirates and later lost her husband in a brutal bloodfest. Then they've taken her to a secret cabin and want her unborn son for nefarious reasons.

James Rollins writes books that are like a cross between Clive Cussler and Tom Clancy. His Sigma Force series is about a special government unit sent in to handle dangerous and sensitive matters. They all begin with an event long ago in history, then transition to the present day; each uses science to make the historical events relative to the modern era.

Blood Line starts at the time of the Crusades with one special knight, one of the original Templars. The next thing we know, the President's pr

Yet another roller coaster of a book from James Rollins. The usual suspects are involved in this story with Sigma Force being seriously challenged by The Guild. This is the book in which the real plans of The Guild is revealed. It involves the hunt for immortality, with much scientific and religious detail used to support the premise on which the story is based. Sigma have two additional helpers in the shape of Tucker and his dog Kane who featured in the novella "Tracker " written to introduce t ...more

I'd never read James Rollins before and for the first 200 pages I was completely captivated. Unfortunately I started feeling like someone changed authors on me. The writing deteriorated, the plot elements seemed to become repetitive and absurd, and the characters turned silly. Finally I skipped to the last chapter and was able to figure out most of what had happened and was glad I didn't plow through the entire book. Too bad. I was hoping to have found a fun new author to add to my list of favor ...more

Okay, it's way too late at night for me to be reviewing books. I purchased this book at the recommendation of a friend of mine (and fellow human-trafficking survivor) who is a HUGE fan of James Rollins. At first I could not put the book down. I was magnetized to it. However, about 2/3 of the way in, I wanted it to be done. Great little adventure; it held me to the end despite my reticence. I borrowed from the same drama as DaVinci Code, though it wasn't as creative or edge-of-your-seat obsessive ...more

Hmmm, let me think: what is this one supposed to be? A thriller? An expose of certain medical experiments? Science fiction? It seemed like there was a bit of almost everything in this one. And while I mostly enjoyed reading this book, I'm not sure I'd highly recommend it.

Aside from the totally unnecessary offensive language and some violence that is more graphic than I enjoy I was pretty well riveted to this book - while I was reading it. But when I finished it and had some time to think, I don'

I read this book in a few days (a plus ). It flows and is good entertainment. The action is ok and allot of it. The characters are very one sided and the story itself seems unlikely to me. I somehow do not connect to stories where the hero's go from one near death to another all the time and somehow manage to survive against all odds. Most of the characters where the super trained commando type, which can beat anything. They do not seem to have any other side. There was a pathetic attempt to giv ...more

It's an ok read. Not as good as other Sigma Force novels. The one theme that continues in this book is that there are a few loopholes in the scientific/historical explanation given by the author. The arguments, though well-researched, are not very strong and convincing and appear somewhat semi-cooked. Anyway, it's a one-time read. If you are a James Rollins fan, then read this. If you haven't read his other books, I suggest reading The Black Order and The Map of Bones over this. ...more

These books are a little far fetched...until you read what is true at the end of the book! But with a little suspension of reality, they are definitely page turners...non stop action with some history thrown in.
