Cain's Blood, the twisted new novel by Geoffrey Girard, is the literary equivalent of an Eli Roth torture-porn bloodbath.
Shawn Castillo, an ex-Special Forces Captain turned mercenary, is investigating a horrific mass-murder at a secret laboratory/ private school.
The victims were sodomized, raped and gutted - apparently by students of the school. The offices and classrooms are awash in blood as Castillo is briefed on his mission.
He's been hired to track down dozens of boys who are clones of histo

Dieses Buch war sowas von unglaublich gut!! Absolut Leseempfehlung. Die Thematik ist einfach so komplex und so absurd, die Spannung hält von Beginn an bis zum Schluss. Man fühlt einfach so mit. Ich hatte so oft Gänsehaut und mir ist es kalt den Rücken runter gelaufen weil das was passiert ist einfach nur unvorstellbar war. Und dann das Ende bzw das letzte 1/4 da haut er nochmal richtig rein. Einfach ein tolles Buch!!

I'm giving this one a 5/5 rating. While not a perfect book, it is one of the most engaging reads of the year and contains some nice moral ambiguities and a realistic, flawed protagonist.


Castillo is an ex-Special Ops member who spent time in Iraq, Afghanistan, and Iran. He's seen and done some bad shit. Even though he's still struggling with serious PTSD, he is tasked by his ex-commander to help track down a group of vicious escaped serial killer clones and their spiritual leader, t

Finally read the full version of this book in its KILLER flip-ARC format. As a companion novel to PROJECT CAIN it sets the stage in a traditional thriller format that is both fast-paced and really, really (really) dark. Probably the best summary of the book was already shared by someone well-versed with thrillers:

“I'm betting the name Michael Crichton will come up quite a bit as people talk about Geoffrey Girard's deeply-twisted debut, CAIN'S BLOOD. And with good reason: Girard appears to have s

Holy cow is this book intense or what?! It had been a while since a book got me scared the way Cain's Blood did. Needless to say I loved it! It's a mix between Michael Crichton and John Ajvide Lindqvist. In Cain's Blood, a bunch of scientists working for government development and research come across a way of cloning the worst serial killers the world has seen. Now, several of them have been successfully cloned; like Jeffrey Dahmer, Ted Bundy, Albert Fish and David Berkowitz among others. When ...more

"I'm one of the few people you'll meet who's written more books than they've read." -Garth Marenghi

This quote is almost certainly true of Geoffrey Girard
Hal Bodner
"Cain's Blood" is a fascinating first novel about genetic manipulation by an intriguing new author, Geoffrey Girard. In the current literary environment of "copy cat" novels, Girard manages to do something truly remarkable by creating an entirely innovative and remarkably creative twist on the old "Boys From Brazil" plot line.

I read this book as a possible nominee for the Bram Stoker awards in the "First Novel" category. Oddly, some of the same elements that make Girard's book highly recommendab

I received an e-copy of this book from the publishers on Edelweiss in exchange for an honest review.

When I received this book, I was so anxious to dive right into it. As I read I just became more and more enamored with the story and the overall general story line. I started discussing it with various family members and describing as much as possible without giving away EVERYTHING (we don't take kindly to spoilers in this household), and actually got quite a few people interested. Sadly, I had

I was so ready to hate this book. As I've said before, it has one of the stupidest premises ever. The Department of Defense creates clones of infamous serial killers. Because that is a fool proof plan that won't backfire in any way. Ok, sure, they try to justify it by saying things about all the cures for brain diseases that they got from from kids with crazy brain chemistry. I dunno, it never really feels like a viable reason? Like it's an excuse to hold the book together. Really, there are a l ...more

I always wonder just how many breakthroughs science has experienced because of military need. Granted, most discoveries are always announced in public channels, but I would wager many of them came as a side-effect or result of military experimentation. Geoffrey Girard’s latest book, CAIN’S BLOOD, roots around in this very idealism. But unfortunately for the general population within the book, the breakthrough results of this military experiment are hazardous to the public’s health.

Cain’s Blood is dark, intense, and gory at times – if none of that bothers you, then you’re in for a gripping and riveting read.

When I first read this book description, it completely blew me away – a deeply disturbing, but profound concept, cloning serial killers and using them as weapons. The government also experiments on numerous clones, altering their environments, and the concept of nature vs. nurture figures prominently in this story, along with genetic predisposition.

Castillo is wonderful

Girard opens his book telling us about Mendel (the father of genetics), moving on to the more recent science of genetics, study of DNAs and cloning. I would have liked biology better if Girard had been my professor.

Girard makes three chilling statements even before his story begins:
Scientists isolated DNA factors. "Once isolated, analyzed each factor to understand how it really worked. Once understood, explored how to modify."
The scientist who led the team that cloned Dolly the Sheep, said in

It sounds like a joke; a retired military guy with PTSD and a clone of Jeffrey Dahmer track down a bunch of murdering clones. Somehow, from a ridiculous premise, Cain's Blood turns into an edge-of-your-seat thriller about evil and a debate about nature vs. nurture. A biotech company funded by the US Government has secretly cloned some of the most infamous serial killers in history, Ted Bundy, John Wayne Macy, Dahmer, the Son of Sam... you get the picture. When some of these clones escape, it is ...more

Geoffrey is a local author acquaintance of mine, and I bought CAIN'S BLOOD at his launch party, figuring it would be a nice change of pace from the romance and YA titles I usually pick up.

Oh, man. It was certainly that.

While reading, I can't count the number of times I cringed and thought, "Damn, Geoffrey. This is some seriously twisted, sick-ass sh!t," and yet I couldn't stop turning the pages. Not sure what that says about me. Anyway, I cared about the protagonists, Jeff & Castillo, and th

Couldn't get past the first chapter's lavish attention to gruesome torture-murder scenes. It didn't help that I apparently mistook this book for the companion YA novel Project Cain. It's been a long time since I noped out of a book so fast. It wasn't the violence, necessarily, it was the author's lovingly detailed descriptions of the dead victims and the crime scenes that made me close the book. I kind of wish I had a physical copy so I could burn the thing. I generally have a high tolerance in ...more

Was passiert, wenn Dolly nur der Anfang der Klon-Geschichte gewesen ist?
Was, wenn Wissenschaftler schon längst den Versuch gewagt haben, Grenzen überschritten und Menschen geklont haben?
Und was ist, wenn diese Klone von den grausamsten, brutalsten und gefährlichsten Menschen abstammen, die man sich vorstellen kann: Serienkillern?

Was ist stärker: Umwelteinflüsse oder Genetik?

In short, one of the most disturbing & well written books I think I've ever read. Seriously unique plot - a terrifying plot. A little horror, sci-fi, and non-fiction all rolled up into a great story with strong characters.

Not for the faint of heart. I had to put this down multiple times and take a break.

The overall concept was fascinating for me.

Two books released on the same day: one teen fiction and the other just plain old fiction. Both of them focused on a government conspiracy where a pharmaceutical company (the DSTI) clones prolific serial killers to study the rage gene which they lovingly nicknamed the Cain Gene. Jeff Jacobson (the clone of Jeffrey Dahmer) and Castillo (a PTSD suffering, ex military-man with nothing left to lose) travel around the US trying to track down more of these cl

3.45 Stars. I more than "Liked it" but I couldn't "really like it" because, personally, I am not a fan of blood and gore. So I had to round down ^_~

Finished in two days because the plot and characters were so gripping! And excellently thrilling read when you just that one of a kind feeling of staying up WAY too late reading a guilty pleasure book.

Actual rating: 2.5 stars. This rating is mostly a "It's not you, it's me" rating. It probably didn't help that I tend to spend my time reading YA and romances so it was tough to switch gears to a book that has characters who spend most of their time raping and murdering women. The concept is really interesting and I'd recommend it for people who don't mind their thrillers with a super dose of violence. I do feel like the idea of nature vs. nurture wasn't explored enough in the book. It's mention ...more

Honestly one of of my favorite book series. I have read Project Cain multiple times (usually forgetting to update here) and have even recommended it to my students who take my Psychology class when we get to the Nurture vs Nature section. Obviously this is not a scientific book but as a good "what if" scenario I believe it really holds plausible weight. Additionally, you just really care about Jeff.

While there are issues with the story (yes, I'm looking at you, ending), it wasn't enough for me to dislike the whole thing. Is there some crazy science stuff going on? Yes, definitely. Is there some crazy government cover up stuff going on? Most certainly. Is it enough to make me quit the book? No, not nearly. I found the general idea interesting enough to be able to just go with the flow and I enjoyed the book.

3.7 out of 5 stars

Ein sehr spannenden und doch erschreckende Vision, was Genetikern so im Kopf vorgeht. Die Emotionen und Verwicklungen sind sehr gut nachvollziehbar, obwohl mir einige Stellen zu blutig und zu bildgewaltig dargestellt waren, und gleichzeitig mit einer Unschuldigkeit erzählt, als vom letzten Teekränzchen berichtet wurde.
Es ist ein sehr interessantes Buch, was ich Lesern mit einem Hang zum morbiden nur empfehlen kann.
Dec 28, 2017 rated it really liked it  ·  review of another edition
Great book in overall, however less weight on bloodbath and more weight on the storyline (enhancing and explaining the events in a much detailed fashion) could have made this book even better. I couldn't get rid of the feeling 'Where did that come from?' at times. You'll have a good time reading this unless you're too concerned with details as a result of your passionate love of the genre.
A terrifying thriller, and one that is probably much more feasible than I want to contemplate. I nearly flunked the genetics unit in HS biology, but I didn’t have much trouble following the scientific explanations peppered throughout this book. There’s also a companion to this book--Project Cain--that Girard wrote for a teenage audience. I may have to read this one just to see how it differs.
