5.0 out of 5 stars Makes you wonder "what if"
Reviewed in the United States on June 10, 2018

This was a great read. Easy to jump into and early on was hooked on the storyline. Was a fascinating idea that made you really wonder about the possibility of "What if..." In today's world where we have become so dependent on electronics/computers at work and at home it really presents a novel idea. You won't regret reading this one. It's not only thought provoking it has suspense. I was on the edge of my seat on a few parts.

4.0 out of 5 stars Not a typical Koontz novel
Reviewed in the United States on August 3, 2018
Verified Purchase
Somehow, this didn’t seem to be a typical Koontz novel. However, the reason I gave it four stars instead of five is that it was a little too dark for me. Normally, I love Mr. Koontz’ main characters, because they are usually self deprecating and a little humorous. But the main character here was neither of funny or likable. Of course, the story wouldn’t have worked if he was funny or likable but it was just not my cup of tea. I probably should give it five stars but I didn’t enjoy it that much so I really couldn’t. The reason I did not like it wasn’t because it wasn’t written very well, which it was, and it did keep you on the edge of your seat, I just don’t like this type of story. Mr. Koontz Is one of my favorite authors so I feel guilty not giving him five stars. A lot of people are going to like this book and will give him five stars and I can understand why, but I just couldn’t.

3.0 out of 5 stars Like I said before
Reviewed in the United States on October 26, 2016

It’s time for another Dean Koontz book review. Today’s edition is another early one (I am reading his books in a row with other authors as well). The book in question for today is Demon Seed. Let’s get to it.

Synopsis: In the privacy of her own home, and against her will, Susan Harris will experience an inconceivable act of terror. She will become the object of the ultimate computer's consuming obsession: to learn everything there is to know about human flesh.

Like I said before, this is a very early book by Dean Koontz. For it be that early, the writing was exceptionally well done. And that was the best part of the book. The way Dean made the intellectual computer sound and lay out its plan was masterful. Even the way Susan dealt with the sociopathic computer and the ensuing danger was the right way.

The thing I didn’t like was that everything was shown through the computers eyes. From what I understand, the version I read was the updated version done in the ’90s. The original told what Susan was thinking the entire time as well.

To add to the point of view there are a few grammatical errors here and there, but not enough to completely destroy the story. Just enough to notice that the book was rushed. Dean Koontz puts out several books out a year. So, a few errors are enough.

I would suggest this book if you have a spare couple of hours. It is a quick read.

Rating: 3 out of 5

I love Dean Koontz when he is at his most frightening self. It was excellent story telling. Kept me from watching Game of Thrones which is a high complement.

Very chilling proposition. Can almost come true. Makes a person think twice about artificial intelligence. Thought provoking in a bizarre way. This is the second time I have read this book. Good entertainment!

In the era of “me too” this book hits very close to home. I hope there is no more of this book in me than I admit to myself.

And if I had an Alexa, I’d be taking a hammer to it right now.

3.0 out of 5 stars The Kindle Version
Reviewed in the United States on June 14, 2009
Verified Purchase
I read this a long time ago in paperback. I don't remember how long it was, but I don't remember it as being a very thick book.

However, the Kindle version has line spaces between almost every sentence. It was rather annoying to have to turn pages so often.

I am a fast reader so I was having to turn the page every 3 seconds; it almost felt like I was playing a video game instead of reading a book.

The 3 stars are mainly due to this issue, but also, due to the story itself.

The ending was rather abrupt. I think I would have liked a little more of the story, even throughout. Overall a good read, though.

The story is set out post the main events of the book as the AI, Adam Two or "Proteus" as he likes to be called is in a virtual court of sorts, explaining what happened in Susan's home. He takes the helm of the narration and I adored the way his enraging emotions took over his speech and he'd repeat himself constantly especially when pining of his love for Susan. He'd screams at the reader (who he addresses as Dr Harris - ex-husband of Susan) to shut him off or keep him alive. This was a very unique story for me as I hadn't read anything like it before. I highly recommend this novel if you're a lover of AI, sci-fi or horror.
