I finished reading "The Ring" by Suzuki Koji a while ago, and I have rarely read a book that caught me like this.
Having seen both the Japanese and American adaptions of it (which both differ dramatically from each other, and even more dramatically from the book), I was quite excited to read it, because it was already one of my favourite horror stories (in fact, the American film was the first film in approximately ten years -if not more- to give me nightmares!).
The basic story is the same in the book and the two films. Four kids die of unknown circumstances at precisely the same time in exactly the same way. This is brought to the attention of a journalist (Asakawa), who is the uncle (or aunt in the adaptions) of one of the victims. In the course of his investigations, he finds out that the four kids spent a weekend together at a cottage in a remote location somewhere in rural Japan. He decides to spend a night in the same cottage and finds a video tape there. It consists of seemingly random and unrelated images, along with a message saying he will die a week after watching the tape unless he follows the instructions. Unfortunately, the instructions have been taped over with a commercial, presumably by the four dead kids.
Asakawa takes this very seriously, because all four kids who have been in this cottage died a week later, and everything seems to point out that they have also watched the video tape.
He teams up with an old highschool friend of his, Riyuji, to investigate the backgrounds of the tape. Having only the images of locations and people on the video tape to work with, they follow a track which leads to a psychic and her daughter, Sadako. And they discover the entire, awful truth behind the tape...
For those of you who have seen the film, be advised that, while the outcome is almost the same as in the film, the background isn't. I'm not going to give away more because this is one of the most rewarding horror stories ever.
The plot culminates in one of the most exciting ideas I have ever heard about. I wish I could discuss this here, but that would mean giving away a good part of the suspense of the story. In fact, what I think of as so exciting just seems to be a minor detail of the whole thing, but when you start to think about it, it makes the whole thing even scarier. And I can tell you, it's not in the films!
Not to mention, the final pages of the book are quite thought-provoking as well.
