I dont know if the other people who liked this book are just dim, or havnt read any good suspense fiction. This book was a big disappointment. I bought the book based on the jackets description, hoping that the Interesting sounding maximum security prison of the title would feature prominently in the story. However, the "tower" only serves to set up the plot and has no real significance in the story. There are some interesting characters in the prision, however their appearances are quite brief. Besides this problem, the book has 3 major flaws. First, there are no likable characters in the story. The "hero", jade, is a complete a-hole. we are supposed to believe that a traumatic childhood incident made him the way he is, however it does not explain his complete and utter disdain for everyone that he comes into contact with. A high point was when he tells a distraught widow to "start dating." Lovely. Another problem with the story is the lack of suspense. Its just one big cat and mouse game until the end. You know that the ultimate confrontation wont come until the final pages of the book, because obviously there would be nothing left to write about once either the killer or the hero are disposed of. Finally, another problem with the story is the lack of any real pay -off. After suffering through the entire thing, you hope for some kind of final revelation which might reveal something interesting about either or both main characters. However, there is no final note of interest, and the story simply ends. This story does not compare to "silence" in any way. The only people who should make this comparison are the books promoters. Actually I suspect that some of these 5-star reviews were written by them! Hope jade finds a good therapit and retires early. I know a good Freudian psychotherapist who may be able to help him.
