Susan Harris lived in self-imposed seclusion, in a mansion featuring numerous automated systems controlled by a state-of-the-art computer. Every comfort was provided, and in this often unsafe world of ours, her security was absolute.

But now her security system has been breached, her sanctuary from the outside world violated by an insidious artificial intelligence, which ha

She's always been controlled by someone or something else, and she wants to finally have control over everything. Alfred is a good example of that. She says "Alfred, turn the lights off" and she knows he'll do it...until he doesn't of course ;) That's why the premise is so scary for her because she thinks she has finally gained control and then she's held prisoner by an invisible intruder.

This is my kind of twisted humor!!! Ha Ha :-)


I read Demon Seed for the third time December 2018, ahead of it being featured as the Koontzland - Dean Koontz Group Read in January. Demon Seed is a fun science fiction story with a dark sense of humor. The relationship and possibilities regarding humans and artificial intelligence was explored by Dean Koontz in 1973 and updated in 1997. The 2009 afterward is an enlightening addition to this wonderful work. Well worth reading.

I listened with an audiobook this time. It makes spirits more evident, sounds not as secure in the dark & in Susan Harris’ house, as Alex protects her. The spiritual voice & approach is more evident in the audio.

I did not remember this was a movie (below).

This book is told from the perspective of a computer system that develops an unnatural obsession with its owner. At least I assume it's a computer system. It was never quite clear if it was a computer, a network, a security system, a house, or all of them.

So, I have a theory of how this book came into existence. Miss Romance novel just went through a bad breakup with Mr Horror novel, so she got drunk and slept with Mr Science Fiction novel, then whoopsie, Miss Romance novel's pregnant!! Who's th

I've always had something of a love-hate relationship with Dean Koontz. When he allows himself to be dark and edgy, giving his imagination free reign, he can rival just about any horror author out there. When he gets self-conscious and plays it safe, however, allowing the morality of the tale to tale precedence over the story . . . well, more often than not, he gets violently tossed into the did-not-finish (DNF) pile.

In many ways, it's as if he is one of his own creations, a schizophrenic author

I absolutly loved how this book was written. It is a unique story in and of it self. Dean Koontz is one of my favorite authors I have read. I have read 5 books by him so far and each one had a great story.

This book is about an evil intelligent computer breaking into a woman's home. It is actually set after the events of the book since the computer is telling the story to his creator. I won't say anymore about the story of the book. I might had given too much away.

Oh dear, this has to be the worse and most badly written book I have EVER read. Seriously, it makes Twilight look like the best book ever written. I have no idea how this was published but it was such a waste of paper, in my honest opinion.

This book is told in a computer’s POV, which could have been interesting but no. The computer literally repeats it’s self 1000 times in this book., It’s the same lines over and over again. Also, when the computer wasn’t repeating it’s self, the rest was reall

Right, before talking about 'Demon Seed' I am now doing a re-experience of my Dean Koontz books when they were unearthed from my attic a few weeks ago. I experienced Dean Koontz quite some time ago. I started reading his work when I was in school. A few I rank as some of my all time fav books and loved his work when I read them. But I haven't read them in about 5 to 9 years and tas

First published in 1973, this techno-horror by Dean Koontz is ahead of its time. The premise is simple and spooky; a house controlled by a sophisticated AI developed by its owner becomes corrupted by a rogue virus which has an intelligence all of its own and a desire to feel 'human'.

For home owner Susan Harris, a nightmare ensues as the AI steadily takes over the house, trapping her inside while also controlling a human minion (a defense force experiment who has been infused with nanite tech) w

Dark, twisted, weird, creepy, and a little cheesy. With how many negative reviews there were I was expecting something horrible. It wasn't bad at all. Some parts were a little uncomfortable to read and left my skin crawling but is that necessarily a bad thing and worth giving it a lower rating?? I don't think so. It can be repetitive and as mentioned before, pretty cheesy but it's still a good read that left me really creeped out.

A creepy little tale told from the viewpoint of the computer, Proteus, itself, with no distracting voices to question its narcissism. It's also, effectively, a satire on men's attitudes toward women. Proteus dreams of filling the world with clones of himself - I think he may have finally got his wish.

I first saw the movie. I liked it. I was surprised to learn that it was a screen adaptation of a book - while it has its flaws, it was overall enjoyable. Koontz usually has great problems with endings, but not here - loved the ending ! Actually it's worth to read the book alone just to see it.

I can literally NOT finish this book. I have never been so turned off by a book before in my life, and I even suffered through Fifty Shades. Lord, I loved Odd Thomas but this is just way too much. I need brain bleach.

This vintage Koontz, although rewritten since it's first publishing was a very fast read, and I liked that, a story with a punch that I got through in less than a day. In a nutshell it's a tale about Susan, a woman who was a survivor of abuse as a child from her father and then from her ex husband. She sealed herself off in a mansion with sate of the art computer system that was supposed to protect her from everyone. The whole house was monitored by Proteus, the ultra smart computer system, one ...more

I'm normally a huge Dean Koontz fan and I buy every book he writes. I came across Demon Seed and realized I hadn't read it, so purchased a used copy. Ugh! The copy I read is the re-write Mr. Koontz did in 1997 and maybe he should have left it the way it was? I found this to not be frightening in the least, and telling the story from the point of view of the computer (AI entity) was just, well, boring. It (he, he defines himself as male) keeps repeating himself over and over. I'd love to get my h ...more

This book to me was a little weird. My favorite character in this book was the guy that was working for the computer. He would steal body parts so that he could make a whole body for the computer to become human. My least favorite character was the computer. He obsessed over something he couldnt have. This book I maybe would read again, but its not for sure. I would recommend this book to anyone who likes Dean Koontz books and horror books. The part of the book that kept me reading of course was ...more

I almost gave this one a four-star rating, not necessarily because it's a great read, but because it's entertaining while also being relatively "quick." If I had been forced to invest more time, I might actually have gone with a two. So, I guess what I'm saying is...it's one of "those." Those books that you know in your heart you'll never think about again, those books that haven't changed your life, that haven't offered anything new, but that you still had fun reading. The plot is laughable, bu ...more

As an avid Koontz fan (that sounds nasty, doesn't it) I enjoyed "Demon Seed." I haven't read all his stuff and almost passed this one up because, um, "Demon Seed"?!? But I was out of books and the library was closed, the book store was closed and the grocery store was open. What would you do?

This is a quick read and, okay, not very deep. It has all of the Koontz humor and quirky dialog. The main character is a computer who has all the characteristics of a sociopathic, spousal abusing monster wit

This was a fast and fun story that I would enjoy reading again. Koontz writes in such a way that it really gets my blood pumping. I had the hugest smile on my face when the "wet music" happened. The only reason it didn't get 5 stars was because it ended so quickly! the last chapter could have had so much more detail. He spends alot of time deeply describing some things that, in my opinion, are not important but rushes through the ending as if the climax doesn't matter at all. Regardless, it was ...more

This might just be my favorite Koontz novel I've read to date. Not necessarily because I feel it's the best, but because it's so different from the rest of his work. He stepped so far away from his formula of hero-crisis-on the run-showdown-happily ever after. That being said, it's a scifi book, which is a genre that tends to only appeal to it's particular niche of readers.

I was completely facinated with the novel, but you might want to take that recommendation with a grain of salt.

This book pretty much sucked. My son lent it to me, and he doesn't lend me his reading material lightly, so I finished it. Mercifully, it wasn't a long book. And it was repetitive-"let me out of this box let me out of this box" etc etc. Though I have to admit the idea of the story was a good one, (intelligent computer tries to make itself a human body to inhabit) the execution was not.
Don't read it. Apparently some of his other books are better.

I read this book in one day (as I predicted). I will now be looking for a copy of the original book released in 1973 as I am interested to know how much was changed in the re-issue. I had a hard time at the beginning of the book getting into the narrative, but that changed a few chapters in and I was once again enthralled with the plot. Not one of his best works for sure, but an interesting read none the less.

I'm genuinely surprised at the number of negative comments about this book. It's horror, it's intended to be horror, and it certainly scared the hell out of me. It kept me on the edge from page 1, and I was so tense towards the end that I accidentally tore one of the pages. Excellent work. Great job. Loved it!
