dude, yeah, i know. dean koontz? me?!?
yes, i am serious. this is one of THE scariest books i have ever read. i finished it in one night while i was living alone, and i had mascara-stained tears running down my cheeks by the end, i was so terrified.
to clarify, dean koontz is not a "great" writer. in fact, some of his descriptive passages are so bad they nearly threw me off course.
howEVER. the scenario he has laid out in "intensity" feeds off of every human being's worst fears: being trapped, b...more

This is thriller suspense at its best. Dean Koontz knocked my socks off with this one, and as soon as I started reading, I could not get through it fast enough. Pages burned and I might have had to stomp my book out a few times.

In a way, this is not entirely typical for Dean Koontz. Don't expect anything supernatural or overly bizarre. It's about a killer and a survivor.

The title holds true to its pace. This book does not slow down once it kicks into high gear. It'll freak you out, and there's...more

I decided that I would write a little about the books that I finish for now on. This was a very scary story! I have to say that it actually scared me sometimes and that is pretty hard to do. "Intensity" is a very appropriate title for this book, I couldn't stay away from it. Definately a plesant surprise after reading Dean Koontz's "Life Expectancy". This book never let up on it's suspense from beginning to end. If anyone is looking for a good horror, "Intensity" fits the bill. Be warned though,...more
Arguably the best Dean Koontz I've ever read. Which is saying something; I couldn't shut up for weeks about it after I read books like The Servants of Twilight from him.

Untouched and alive. Alive, she may be, but untouched, Chyna Shepherd most definitely is not. Chyna is a survivor. From young, faced with the wild, chaotic whims of her mother and the long line of men she seems to use, Chyna has had an unstable, often violent childhood. From drug deals gone south to the casual murder of an elderl...more

Recommends it for: lovers of blood and gore and scariness
This book is well written, I'm sure. From the moment I started reading it I felt sick to my stomach from the overly detailed homicidal and torturous events, but also I could not stop reading it because the author held a small hope of the heroine doing some lasting good by helping the 16-year-old girl who was locked in this crazy bastard's basement. And of course getting herself out of this situation in which the reader found her.

I am glad I finished it. But I'm not going to hurry to read another...more

Fabulous. Scary. Incredible heroine.

Readers who liked The Girl With The Dragon Tattoo should like this. The two heroines (Lisbeth in Dragon Tattoo and Chyna in Intensity) were similar in their actions. Chyna chose to fight what seemed impossible. Instead of running and trying to get away (like normal people) she went after him with the barest of weapons. She was resilient, resourceful, brave. She called it reckless caring. In the beginning of the story, Chyna is trying to get away from Edgler a...more
The title for this novel is truly well selected since this book is indeed intense! You are barely getting confortable in the beginning of the story when bam!!! the horror starts! I have read quite several books by Koontz and I was shocked by the crudity of the very first scenes. I told myself then, "Dang! He is not fooling around! The villain here is truly a dark human being". And it's also one of the most shocking things in the book, since you don't have any paranormal element here, all the hor...more

Recommended to Chris by: Becky

This started out rough. I had to get used to Koontz's writing style, which to me isn't as smooth a read as others. But once the story got going, I was really interested in it.

Chyna Shepherd is trapped in the house as the killer, Mr. Vess, goes on his rampage. She must deal with not only her fear of being found out, but of a lifetime of insecurities brought on by a sorry mother and a troubled childhood. She must overcome these deeply rooted issues if she is to survive the next 24 hours and if she...more
"Intensity" lives up to its name. Intense from the first page to the last, well written and masterfully suspenseful, it's one of the best books by Dean Koontz.
""God fears me."
I've been reading this book for a while, mostly because I only read it at lunch. Some of it though had to do with the book itself.

I like the story, believe me...It's interesting. The characters however, are not. I didn't care for any of them...if they lived, if they died, if they hurt or suffered or didn't. They failed to generate any emotions in me. I couldn't bring myself to care about them (other than my own inward mocking at the name 'Chyna'...kept thinking of the WWF (WWE, whatever) wrestle...more
Dean Koontz might never win a high concept literary prize...but, I know why he is one of the reigning kings of horror. I read this book 10 years ago (or so) and I still remember how it scared the bejeezus out of me. I lived alone at the time and very comfortably, I may add. I was never one of those "single women living in fear" kind of people. Although i have a fairly vivid imagination, I generally remember that I am reading a book and that the events described within are not going to suddenly c...more

"Fascina-o a forma como a vida das pessoas se cruza fugazmente, com um potencial dramático que por vezes se cumpre e outras vezes não."

O título "Intensidade" pode referir-se ao motivo dos acontecimentos, à própria história, às descrições, às sensações, às personagens e ao sentimento provocado no leitor. No livro "Intensidade", na verdade, tudo é intenso.

A história passa-se em vinte quatro horas e tem apenas duas personagens principais. Porém, as duas únicas visões da narrativa que temos nunca se...more
Intensity was intense at times, but there wasn't a lot going on the novel which spanned almost 450 pages, so most of the writing was about the character's thought processes, which completely pulled me out of the story and very boring, it seems as if Mr. Koontz tried to persuade the readers into thinking a certain way or having a certain feeling rather than telling the story and letting the readers interpret it.

Most of the novel consists of Chyna (the protagonist) going on and on about her past,...more
Being a huge Stephen King fanboy, I am almost obligated to hate Dean Koontz. It is one of the biggest literary feuds, King vs. Koontz, and fans of both authors rip at each others throats whenever possible. Like many hardcore fanboys, I'm ready to tear anyone that likes Koontz apart (at least in my mind), and whenever I meet someone that says they like Dean Koontz I laugh on the inside, HOWEVER! That was my attitude back when I was 13 years old, and now six years later I realize that before I can...more

I like scary books. Stephen King is amazing. Peter Straub easily induces chills. I read Red Dragon—where Hanibal Lecter is first introduced—when I was probably too young and without my parent’s permission. But books don’t scare me. At least not until the night I started reading Intensity by Dean Koontz.

The main character, Chyna Shepherd, has come to Napa Valley with a friend, Laura Templeton, to visit Laura’s family farm. Like me, Chyna finds it difficult to fall asleep in a strange place. So s...more
Intensity. More like intensely boring. I started this, got not even half way through and stopped reading it to read a Heather Graham book that i finished faster and enjoyed way more. Yes, it was better than this long drawn out storyline. It wasn't gross, didn't make me feel sick, wasn't disturbing at all like the other reviews claim. Maybe it just takes more to get to me. I actually liked Vess as weird as that may be. Well, I liked how he viewed things. It was a little weird that it Chyna found...more

When I was younger, I devoured Koontz's novels, reading close to a dozen, although it has been over a decade since I had last read his books. I remember the plot and characters of very few of them. Two stand out to me. One is my favorite, Watchers, whose most memorable character is a golden retriever. The other is Intensity, with one of Koontz's most sinister villains in Edgler Vess and most courageous heroine in Chyna Shepherd.

What's so striking about this suspense novel (and boy does it deser...more

I think I've read too many books abut psychos and I've read about too many gruesome things to be impressed anymore. Or maybe this Dean Koontz book just wasn't for me.

First of all, this I got in a haste from the library, without really looking at the description of the story or anything else, so I expected a different thing than what I got. My bad. I wasn't disappointed, though, in the first.. 70, 80 pages. It actually got better and better and I had the impression that I'm really going to love...more
This is the first Dean Koontz novel I've read. And I didn't really 'read' it, like I'd hoped. Similar to other folks in my book club, I skimmed a lot. I read the first sentence, got the gist and sped over the lengthy descriptions.

He creates vivid pictures and I agreed with one of the group's favorite scenes when Mr. Vess, arms and fingers outstretched is seducing a spider so he can taste and experience its essence and soul. But every scene was treated that way with a lot of description so the re...more

Finished it quickly enough (2 days) to say it kept me on edge and wanting more. I liked the plot and pacing of the story but Koontz has a way of over-explaining things that don't need it. He uses analogies that seem like a reach too often. Too many flashbacks to the main character's past at way too convenient times! It made the story feel forced instead of naturally unfolding. (The beetle, the Key West scene, etc.) While I see the connection made between her past and her current situation as a c...more

I first saw the film then thought why not read the book. Glad I did. The first book I read by Dean Koontz.

While a friend and I were talking about scary movies. She asked if I heard of the film or book Intensity. I wasn't sure but I did remember faintly a film that I saw on TV when I was little of a woman who had on a red sweater, and she was in chains tied up in front of a table and then later she and a girl were on the roof escaping from a man. We then looked up the film and turns out it was In...more

The title says it all. It's a frightening and suspenseful book and some scenes were especially creepy. I didn't like the many long flashbacks that were insightful but disrupted the flow of the story. I also liked the hopeful and inspiring ending.
Intense is an understatement! I read this edge of your seat novel in one day. I simply could not put it down.
Koontz has a knack for capturing your attention right from the first chapter and never letting go.
One of his best works.
It was this book that made me FINALLY realize I don't have to finish a book if it is an agonizing read. Sorry Dean.
Lucy Morton-smith
This book was actually the only book that, to the best of my knowledge at this monent, has ever made me cry. And that goes after reading the end of Odd Thomas, which made both my father-in-law and mother-in-law teary. I do not cry easily in books, however the ending to this was so emotionally powerful that I was moved to tears. And so was my sister. That being said, lets move onto a review actually about most of the book..

The book starts off amazing, and that is how it continues and finishes. I...more
