4.5 stars (AND OH SO CLOSE TO A 5 STAR RATING). This was my first book by Scott Sigler and I now consider myself a fan and will be reading more of his books in the future.

This is a high-octane, fast paced scientific thriller that does a better job than many in this genre on two very important points:

1). I thought the author did a really good job with the characters and the dialogue. Even when nothing was going on with the plot (which was not often) the dialogue between characters kept me enter...more

ANCESTOR is about two deadly killers - one of them is a control-crazed millionaire named Magnus and the other is his lab-manufactured genetic horrors. Magnus was trying to create placid herd animals available to donate organs for humans who need transplants, but a delusional scientist tweaked the DNA and instead made large vicious predators. When Magnus tries to cover-up the project, these beasts get loose. Now everyone on an isolated island is at risk of being hunted down and exterminated eithe...more
I like a good monster story that is backed up by a scientific origin: the experimentation and theory make for interesting reading before yielding the invariably ravenous result upon the poor scientists and support crew. Here, Sigler throws in some passages about DNA and animal-cloning and xenotransplating and species-jumping viruses, going into just enough detail to give his story just enough technical background. All of the high-tech gadgetry surrounding the laboratory and the armament of the a...more
Possibly the most boring, useless book I have ever read.

This book has been out for quite a while but I have only recently read it and I felt the urge to review it.

I spotted this book while searching for something new to read. It was cheap and had a great premise: "Scientists on an island try to clone an ancient monster so they can use its organs in transplants. Everything goes wrong." Sounds good, right? A simple action horror. Something easy to read. Fun.

no no. Fun is not what this book offers....more
This review is for the new hardcover edition of ANCESTOR slated for bookstores in June of 2010.

The new hardcover edition of ANCESTOR follows the same plot line as the original. A group of scientist are charged with creating an animal whose organs can be used for Xenotransplantation. The ultimate goal is to provide organs for the growing list of individuals awaiting organ transplants. To reduce the incident of organ rejections the scientists are trying to create an animal, the Ancestor to all mam...more

This review is for the new edition of "Ancestor," due out June 22, 2010. You can pre-order now!
I listened to the original podcast of "Ancestor" some time ago and thoroughly enjoyed it. This version (June 22, 2010) is even better.

The basic premise is that a company has funded a project to create an animal that would be bred for organ transplantation. An 'ancestor' that would avoid the problems of rejection by combining genes from many, many mammalian species - bot halive and extinc. A fine, huma...more
“Secret Experiment. Tiny Island. Big Mistake”

At its most basic level, the story in Ancestor by Scott Sigler could be described as a number of chases. Firstly, we have the US government trying to track down renegade bio-engineering company Genada, as they try to operate above the law. Then we have the story of evil predators chasing people around an inhospitable island in the dead of winter. It would be really easy to right off this novel as just that, but I strongly urge you not to. Ancestor is...more
Monsters ARE real! But they don’t live in closets or under your bed… they were created by scientists in a lab. DNA combined to create the perfect predator. The only problem is, that’s not what was supposed to happen.

Ancestor tells the story of a good idea gone bad – TERRIBLY BAD! Although the creatures are the stuff of nightmares – and believe me, I’ll never look at a cow the same way again – the really scary thing is that at its roots, the story is not all science “fiction”. Let’s just hope the...more

It was OK, but might have been better with further editing/revision. Predictable and somewhat pretentious, but not bad as escapist reading. Loaded with superfluous simile like poorly selected corpus of quotes. When I'm ill, I'll accept diversionary reading I might otherwise give up on. I did give up on another of the author's books "Infected". I feel Scott Sigler may be better at self-promotion than at writing. When I finished I didn't feel ripped off or that I'd completely wasted my time -- jus...more
I love this book. I cannot stress enough how incredibly plausible this storyline is when you get down to the science of it. Sigler has created a thriller that grips you deep in the primal gut and won't let you go. It's hard to put the book down. The characters are real, either as hateable people you are happy to see die, or likeable people you want to save. There is romance and love without being sappy or corny, and, true to Sigler's MO, there is lots and lots of violence. I seemed to remember M...more
Not nearly enough "ancestor" violence. This is essentially a monster story with two monsters and a dozen or so uninteresting potential victims. The book focuses too much on the flat victims and the uninteresting second monster instead of the titular monsters. The first half of the book is a fun slow burn as you await the arrival of the ancestors but when they finally arrive they play second fiddle to a boring, run of the mill human villain. There is also a chunk of the book devoted to federal ag...more
As a fan of the original version of Ancestor, I was looking forward to reading this new, updated version. It didn't disappoint. This new version shows how much Scott Sigler has improved as a writer since he first released Ancestor as an audio novel, and the original was great! The story is tighter and it's clear he's done quite a bit more research for this release of the story. Ancestor is a thrill ride from the very beginning. I found myself staying up until all hours of the night thinking I wo...more
After listening to Scott Sigler on a podcast and enjoying what he was about, I bought three of his books sight-unseen. I started off with Infection, which was a good story with so-so writing, but finished so strongly that I immediately tackled Ancestor.

As far as readability (and I guess page-turnability), this is one of the best books I've read in a while. Think Dan Brown with a liberal dusting of cryptoscience. I couldn't put the book down, and couldn't wait to get back home to continue reading...more
I got this book as I really like how Scott writes...
This was a page turning book with a good underlying story, which yes, would be really easy to turn into a movie, he gives some great mental/visual!
and yes, it has its cliche moments.... some unbelievable bits too!
but you like or loathe the characters.... and I loved Mookie... she was my hero!
I did end up feeling sorry for the "ancestors" and their mums (not to mention the squirrel)
lots of background story, lots of descriptive on how things...more
I gave Ancestor a shot after reading Earthcore, and it generally works but it's not quite as good. Sigler is very good at coming up with thrilling stories and great spooky locales to set them in, but both books are very cold. The action is clinical and you don't care about any of the characters, and he seems to take unusual pleasure in sadistically killing everybody off. I would hesitate to call them badly written, as I hope he's matured as a writer since Ancestor, but my enjoyment of his books...more

Yet another installment of "Scott Sigler Week Read-a-thon"

SYOPSIS: When a biomed research company is hellbent on both avoiding the regulations of government oversight and leapfrogging their competition at any cost, they remove all safety checks in the name of science and proceed in a revolutionary genetic regression DNA project with the aim of creating a living herd of rejection-proof organs for humans. What results is the typical mad scientist messing with shit they should leave alone and pay t...more
Apr 16, 2012 Bobby rated it 4 of 5 stars  ·  review of another edition Recommends it for: All Michael Crichton fans and anyone with insomnia.
Sometimes its really fun to read a book because it justs keeps you turning the pages. I found this to be the perfect reason to read "Ancestor"!! The characters?? A little unbelievable, but who cares. This is a fast paced story that starts with a bang and ends with explosions and all kinds of excitement in between. This does for stem cell research what Jaws did for the Great White. Gory, Good job Scott Sigler. Oh yeah, and thanks for keeping me up all night!!
I loved this book. The writing was really good, and was really smart as well. The entire book was a thrill ride from beginning to end, it was so hard to put down. There was never a part in this book where I felt bored. It sort of read like it was a movie, and it was completely exhilarating. Some of the characters could have been fleshed out a little more, but it wasn't a big deal. My only somewhat negative comment would be how the characters used the phrase 'eh?'. The author said it was a way of...more
I had just finished the podcast for Nocturnal when I started reading Ancestor. Nocturnal blew me away with the suspense, characters, and monsters, so I assumed Ancestor would do the same. Ancestor is a great story but it doesn't compare to Nocturnal, Infected, and Contagious.

I did enjoy the Asian character and her rising foreboding about just what she was doing messing with genetics. The beasts made the book, though. Intelligent killing machines.
Let me start by saying I'm normally a genre-reader (speculative fiction), and this one is by far too far on the thriller side of stories to be a real genuine love interest for me. Yet it has science fiction elements in it, and I usually enjoy Scott Sigler's writing, so I figured "what the heck" and started reading it.
And I didn't regret it one single second.

Yes, there where the stupid chapter headlines again, as I already knew from Infected and Contagious, but it wasn't as bad this time, or I s...more
Became addicted to the author with his "Contagious" trilogy. For me, it is right up there with "The Stand" and "Swan Song" in my favorite apocalyptic tales of all time. And it is a very hard choice as to which would be number one.

I came across Dr. Feely in "Pandemic" and was pleasantly pleased to find his story had started with "Ancestor". Still can not decide if I like the guy or not!

I am not one to give a synapse of the story, you can read that on amazon or some other review. For me, its ju...more
Freaky let me tell you. Sigler is not afraid to develop a character then kill it soon after. This would make a good movie.

I read Ancestor simultaneously with my husband, a definite non-reader. I bought him the paperback for his birthday and I also had a copy on my Kindle because we both LOVED Sigler’s last books Infected and Contagious. (What can I say? To a bookdork, there is nothing sexier than a guy who will read with you…)

Since sharing books is such a rarity, I never shove books at him unless I’m convinced he’ll like them. Infected and Contagious were so creepy good, that I was SURE we’...more

As he did in Infected and its sequel Contagious, Sigler continues to mine the landscape where medical thrillers and hard science fiction cross-breed. This time, he throws a little cabin-in-the-woods slasher flick DNA into the mix as well. The short version of the plot, without giving away any more than the cover copy does: after a lab experiment goes awry and a debilitating cross-species virus almost escapes, a US cover military team starts shutting down all private research facilities working o...more

I like Scott Sigler’s blend of action and intelligent plots. Ancestor is almost like Crichton’s Jurassic Park in that he investigates genetic engineering and how that could go horribly wrong in the pursuit for profit and scientific praise.

I really enjoy the learning side of a novel and in this we get some scientific detail about genetics woven into the tight plot. It’s not too technical but enough that you can appreciate the researc...more
I'm a huge fan of sci-fi thrillers where man plays God and the creature they create fights back, so I was really looking forward to this book. Unfortunately, it fell a bit short of my expectations.

This wasn't a bad book by any means; I just feel that it had the potential to be a great book and just never quite got there. I was glued to the pages during the scientific explanations (I'm a nerd), and when the embryos inside the cow started acting unusual. However, the book was bogged down with way...more

Antes de ser um autor publicado e bestseller, Scott Sigler, como muitos outros, foi recusado por várias editoras. Incapaz de cruzar os braços, Scott Sigler aventurou-se por outros caminhos, tornando-se um dos primeiros autores a disponibilizar, gratuitamente, os seus livros em podcast, capítulo a capítulo. E foi assim que ganhou uma legião de fãs e, mais tarde, acabou por ser publicado com muito sucesso, pelos meios tradicionais.

I loved this book! I have always had a thing for science fiction, but it's been a while since I truly indulged in this genre. Clearly, this is not high-end literature, but let's not be snotty, this is a jolly good romp. The book gets a point deduction because sensitive readers might get the wrong idea about science and research, no matter how clearly it is stated that this is a run-away, non-condoned mission which is also being chased by US military to be forcefully shut down.

The idea is to gene...more
I am amazed and wowed again by another one of Sigler’s books. This one will definitely be on my favorites list. Not only did it have a perfect blend of science, horror, and action, but it was well written and it definitely grabbed my attention from the very start of the book. I really liked how there was a buildup of suspense throughout the first parts of the novel. Obviously, something didn’t seem right from the start but the suspense was very well done and everything just exploded (literally a...more
What if a biotech company finally found a groundbreaking solution to our current world shortage of viable transplantable organs? What if they were able to ensure these organs were genetically free of disease and defects by creating 'Ancestor' mammal as the incubater for those organs? Sounds intriguing, almost altruistic. But what if the timeline to market were stressed and shortcuts had to be taken? What if greed and hubris became the impetus for the project rather than a true desire to save hum...more
