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

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

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

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
Jaclyn Hogan
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.

I first heard of this book due to it's young adult companion novel, entitled Project Cain. So I figured that I would try and read the adult novel.

Boy oh boy oh boy....

First of all, I want to know what sick and twisted mind first thought of this plot. Serial killers as bio weapons? REALLY?!!! I hope someone doesn't read this book and actually decides to carry out this plan. Seriously, I will off myself if this happens! Now on to the general plot

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

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?
Diese Frage stellt sich auch in Geoffrey Girards Thriller "Verdorbenes Blut" nicht nur dem Leser, sondern auch dem Hauptakt

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

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.
Cain's Blood by Geoffrey Girard is a book about scientists coming together and making clones of the most notorious serial killers. The Scientists took the DNA of Ted Bundy, The Sons of Sam, The Boston strangler, Albert Fish, Henry Lee Lucas and put they DNA in little boys. The boys where set free by the scientists by accident, it's a program that a bunch of boys who doesn't know their heritage but it's a evil heritage.

I have read the majority of this book, full disclosure. I then had to return it to the library through the inter-library loan system and have not been able to get it again.
This book is not for the faint of heart. I've wanted to read Joyce Carol Oates' fictional account of Jeffrey Dahmer for a year or two and many reviews said that they would not allow it to be inside their house, it was that terrifying. They had to put it on the porch or anywhere outside.

Ein Spitzenthriller, der den Missbrauch der heute möglichen Gentechnik anprangert und sehr gut recherchiert wurde. Die darin erwähnten "Militärexperimente" an der Zivilibevölkerung verschiedener Länder hat es tatsächlich gegeben (und gibt es vermutlich immer noch). Manipulation und Konditionierung zur Gewalt gehören dazu.

I'm going to write one review for Project Cain and Cain's Blood since they are companion novels; the former is a YA novel, and the latter is written for adults. I read Project Cain first and followed it with Cain's Blood; I read both books in two days. I enjoyed Project Cain more than Cain's Blood. This could be due to the fact that I read it first, and the two novels share some of the same passages that I didn't need to reread in the second book. However, I think it has more to do with the firs ...more

Mr. Girard's first published novel, Cain's Blood is a scary peek into man's nature and what can happen when it's combined with the technology of cloning. A twisted thriller that keeps you turning pages. Is our anger natural or is it brought about by environmental influences? Once you're are trained to kill can you love? And what if you're born to kill? Geoffrey Girard weaves a fascinating tale that will get you wondering what those scientist are doing in those shiny, secure facilities with Gover ...more

Jeff Jacobson's father sat down on the bed with him one day, and told him that the people whom Jeff had thought were his parents for the past sixteen years weren't his parents at all. Instead, Jeff had been cloned eight years before from the DNA of serial killer Jeffery Dahmer to be developed in a vat of liquid as an eight-year-old boy. Then "Dad" left an envelope of money on the bed, walked out the door, and Jeff never saw him again.

What follows is the most horrific, awful, gut-wrenching piece

If your worst fear is that the government will clone Ted Bundy this is the book for you. I had a hard time sleeping at night. At the same time, I couldn't put this book down. Scary. Creepy. Disturbing. Entertaining. Interesting. (Are serial killers a product of nurture or nature or both?) Lots of science in this book, lots of talk of government conspiracies, lots of action and gore. I especially appreciated watching a relationship develop between the solider, Shawn Castillo, hired to capture a b ...more

This was average at best. I truly wanted to believe in this story. The idea of using the DNA of America’s most infamous serial killers was very exciting. This book has the potential to start a series of novels focused around the protagonist Costello. I believe we could have enjoyed several novels where Costello hunted down serial killers with a mix of ShowTime’s’ Dexter and Mayberry’s Joe Ledger. Costello’s could have developed into a very dark hero that enjoys killing these serial killers and w ...more

- Ansprechender Plot (von bekannten Serienmörder-Genen geklonte Jugendliche)

- drastische Schilderungen, die an manchen Stellen an Richard Laymon erinnern
- regt sehr zum Nachdenken an und wirft moralische Fragen auf

While this wasn't really what I'd normally call a 4-star read, it was so much better than Project Cain that I had to give it at least 1 more star. Project Cain read like a summary of another book - this book. This is the fully fleshed out story of ex-soldier Castillo and his assignment to hunt down a group of clones created from serial killer DNA, and his unlikely sidekick Jeff - a clone of Jeffrey Dahmer.

I feel like Project Cain is redundant. With the exception of the (view spoiler)

This book was really disturbing, and I like disturbing, but really? I liked this book, but it's not for the 'faint of heart."
If you like murder/mystery/science/cloning, then you would like this book. It's scary, because science and technology never stops progressing. It keeps going forward. What if we could clone serial killers in the name of science and national security? Would the world benefit or would there be chaos and terror? I couldn't put this book down and I couldn't stop thinking about
