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
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

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

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
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!"

I jumped into this book less than a week after finishing the previous installment. Usually, I read about one of these every eight months or so; however, the epic conspiracy suggested in t

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
In his latest addition to the series, James Rollins, picks up right where the last book left off. This time Grey, Seichan, and Kowalski are sent to Somalia, in search of the President's daughter who has been kidnapped. Along the way they pick up two new characters, Tucker Wayne - a former Army Ranger, and the comabt dog he trained, Kane. Like all of his novels, Rollins, sends the Sigma Force operatives on quite the roller coaster ride, throwing in copious amounts of real world science. While you ...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
First time mothers are supposed to spend the nine months before birth in a blissful state of anticipatory preparation. With only a few weeks before the arrival of her newborn, Amanda is feeling anything but bliss. After discovering her husband's infertility, Amanda undergoes the grueling process of in vitro fertilization. A couple miscarriages later, she finally carries a healthy child. Despite all of this, she and her husband are fleeing for their lives. A few weeks ago, she received anonymous ...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'

First Line: They once called her a witch and a whore.

Author James Rollins brings us the eighth adventure of Sigma Force, an elite covert arm of the Defense Department composed of former Special Forces officers who've been trained as experts in various scientific fields.

Once again that fascinating organization of old, the Knights Templar, provide background for a novel. Of the nine original members of the Templars, only one is not known by name-- and that is the member Rollins weaves his story ar

Bloodline, James Rollins 2012

How and why would "The Guild" kidnap the {resident of the Untied States pregnant daughter,and what would they do with them? This Sigma book, featuring all the usual people from Sigma, we are also introduced to adjunct members: Tucker Wayne (an AWOL soldier), and his four legged constant companion Major Kane. The book begins with a Somali kidnapping at sea, travels to the Somali mountains, and then back to the states. We also finally get a glimpse of who really runs "

Blood Line is the latest Sigma Force novel by James Rollins. The Sigma Force - Grey, Sechan, Kat, Monk, Lowalski, Lisa and Painter, are joined by ex-military Tucker and his heroic war dog, Kane.

To complicate the situation, President Gant is suspected by the head of Sigma, Painter as being the head of the Guild. The Guild is the shadowy group that endangers the safety of the world and Sigma. This is by far the ...more

I have been reading James Rollins for years, and I’ve read all of the Sigma novels, so I feel quite comfortable in saying he has outdone himself this time.

When the president’s daughter, Amanda Gant-Bennet, is kidnapped by Somali pirates, Sigma is put to the task of getting her back. At first, it is believed the kidnappers don’t know who they took, and the mission is kept on the down-low in order to keep her safe. Once the Sigma team reaches the secluded African compound where Amanda is being he
Another great ride by James Rollins, this Sigma book is notable for introducing two new characters and for making women the focus. Rollins has always written great female characters, strong, capable and smart, complicated and full of depth. But this is the first book that places Kat and Lisa as the action-drivers while Painter is busy researching and Monk is home watching his young daughters. Kat and Lisa are trying to infiltrate a fertility clinic with links to the President's family and his ki ...more

Recommends it for: Todos os apreciadores de bons thrillers tecnológicos com muita ação.
Um excelente tecnothriller de James Rollins da série "Força Sigma", uma organização secreta americana que efetua missões de natureza mais sensível ou complexa. Neste livro, Rollins debruça-se sobre o interessante tema da "imortalidade" humana, encarada da perspetiva do prolongamento da duração da vida humana resultando numa longevidade de várias centenas de anos. Este contexto permite ao autor explorar, e aplicar à narrativa, um conjunto de tecnologias muito recentes, tendo o autor manifestado u ...more

This is the latest Sigma Force thriller from Rollins. Since this one is focused almost entirely on the group's main adversary, it does help to have read at least some of the more recent books in the series, to understand not only the subtle relationships between the group, but also the history with the Guild, the arch-nemesis of Sigma. Sigma is a shadowy governmental force, buried deep within DARPA, which is comprised of Painter Crowe, the leader, with his girlfriend, a doctor named Lisa, Grey P ...more

I enjoyed the book as I do all James Rollins books. He is a master at keeping a fast-tempo in his novels. Normally he is a master at blending the perfect amount of history with science with all of the thrill of an adventure but unfortunately in this book, he didn't blend as beautifully as before. In my opinion, there was so much action that it took away from the science and historical aspect which makes his novels such a joy to read. He seemed to have placed all of his normal work in the last 4

ScienceThrillers Review:
James Rollins does it again with an action-packed, can't-stop-reading thriller loaded with plenty of science-y plot elements. The Sigma Force series is now eight volumes deep; Bloodline continues the team's adventures and follows their personal lives. Thi
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
Rollins is back and much better than ever!

Continuing the big "Echelon" story arc from The Doomsday Key and The Devil Colony, the True Bloodline at the very heart of the dreaded international terror group known as the Guild has been revealed to Sigma Force Director Painter Crowe. It's the family of sitting US President James T. Gant. At the end of the last novel, it appeared that the Gant family, including the President himself, was secretly evil. And, in between the usual historical prologue and

When the president’s daughter, Amanda Gant-Bennett, is kidnapped by Somali pirates, SIGMA, a government secret agency, is put to the task of getting her back. At first, SIGMA believes the kidnappers don’t know who they had taken captive, and the mission is kept low-key in order to keep her to not accidentally spook the enemy pirates. Once the SIGMA team reaches a secluded African compound where Amanda is being held, however, they realize that a much bigger plot is in the works. Through this plot ...more

Normally, when I purchase a James Rollins book, I am in an airport about to board a plane. Then my nose disappears into the story and I barely come up for air until I've finished the book. Two days tops, maybe half the book on the flight out and the other half on the flight home. This time, I won my copy of Bloodline in a blog contest by Seeley James, by answering a question about female heroes and how they are portrayed by Hollywood—specifically when those females kill. Seeley said Hollywood wr ...more

Have you ever read James Rollins before? If so, then you may expect tantilizing plot twists, adventurous protaganists and down right scalawags for villians. If I've assumed correctly then, this is the book for you.

So why did I only give it 3.5 stars?

I had never read Mr. Rollins work before ( I know, I know...gasp! How could I?). So for a newbie this book was a little much for me. Although the historical stuff at the first caught me. I think I would have enjoyed this more if it had been histori
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 as this one promised to be the Finale of the ongoing Sigma Vs. Guild war, and boy, did it deliver! Now, Bloodline is a bit DIFFERENT as in there's actually NO historical trail to follow along with scientific trail like the previous SF novels, and although it did have a historical prologue at the beginning, it came in play just before the ending. So it almost felt like a ...more
This latest outing of the Sigma crew lives up to its predecessors and shows why Rollins is one of my favorite series authors in the thriller field. The usual gang is all here and doing their usual good Sigma work and battling their own personal demons and issues, and we meet a couple of new characters of the "a man and his dog" variety. And they make wonderful additions here, even if it's only for the one outing. (Or is it?) The overall story is interesting and fun and is plausible enough, altho ...more
I'd never read James Collins 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
Bloodline is one of the best reads you can have during the summer. It is as exciting as Jurrassic Park or The Firm. I couldn't put the book down once I got it. I have both an autographed hard cover, and an ebook. I enjoy Rollin's world so much, and love the new characters of Tucker and Kane. It is an unmitigated treat every time Rollins has another book published.

If you do get a hard cover book and wish to have it autographed, please go to and follow the
