5 stars - want more, more books, more movies about the books, more movies about the authors and the making of the movie, just more!!!(less)

some of these comments are way harsh! i don't know if I've ever read any of his other books but my mom owns every single one so i borrowed this one to kill some time on a nice day. i ended up reading it all in one sitting. while the story is a little outlandish it did keep in the edge of my seat and i wasnt bored. it is a quick read and i thought it was worth the time

Fast paced... Slightly frightening in places. Though really just a fluff book it made me think a lot about people and how we view what's 'wrong' or 'right.'

Entertaining to a point but required a bit too much suspended belief. Just not my style of book I think.

Good book. Enthralling story! It's like a psycho thriller/horror/mystery all wrapped up into one. Definitely a must read!

Relentless is a classic Dean Koontz novel with some small variations. It’s written in first person, which is unusual for Koontz (I can only think of one or two other novels he’s written in first person voice). It has a great cast of characters — Cubby (the narrator), his wife Penny, his son Milo, and their dog Lassie — and a villain who is unique and interesting through most of the book.

Unfortunately, when the mystery is revealed, it’s a lot like ones Mr. Koontz has done a few times before, and I was disappointed in that. I was able to predict most of what happened at the end before it happened, which is unusual for a Koontz novel. Perhaps I’ve just read too many of his books, and am too used to his style. But this book’s “reveal” will not be a big surprise to people who have read some of Koontz’s other work.

The novel is well worth a read, and I enjoyed it… but the ending left something to be desired, by my lights.

I hate feeling obligated to finish a book because this one I should have stopped after the second chapter.

I absolutely adore Dean Koontz's books. Like many other reviewers, I have read much of what he has published.

Relentless, while being a decent read, falls short of what we know, love, and expect from Koontz. There were no twists, oddities, suspense, or intriguing moments and the book was thoroughly happy without bringing the reader any since of fear for the characters or the situations. Dean Koontz tends to bring the reader through spirals of anticipation and captivation, but there was none of that in this book. I love how Koontz typically hooks his readers into obsession with his writings, but Breathless did not follow this trend. This book feels rushed and is unsatisfying. I hate to admit it, but I'm starting to believe that if I want any satisfaction, I'm going to have to start rereading his older books.

On a side note, I realize that Koontz writes canines into his books, typically giving them unnatural abilities, but in this book the dog was unnecessary. Having the dog in this book with the selected abilities makes me wonder if Koontz wrote this book at all. The dog seemed to be stuck in simply because there usually is a dog in Koontz's books, not so much because the dog added to the story. Idk, that along with the shabby ending and weak introduction of characters makes this book feel as if the writer rushed through it simply to meet a deadline. Sorry Koontz.
