Review From User :
Dean Koontz writes two kinds of books, good books and brilliant books, and this was one of the latter. It was gripping from beginning to end, all 750 pages of it, and I found it unputdownable. I really enjoyed the fact that the two main characters were genuinely strong, intelligent people who played the baddy at his own game and did not constantly do stupid things. And I loved that after all the tension and stress Koontz still allowed the reader a satisfactory and happy ending. I read to be entertained and this book for me was pure entertainment.
It’s a fear more paralyzing than falling. More terrifying than darkness. More horrifying than anything you can imagine. It’s the one fear you cannot escape, no matter where you run . . . no matter where you hide. It’s the fear of yourself. It’s real. It can happen to you. And facing it can be deadly. “Fear for your mind”.
