I usually don't like science fiction because it is so out there. However, inventing artificial intelligence isn't really out there anymore and this book was very plausible. I didn't see the end coming but it was very compelling and realistic. The age of computers can have it's scary side, especially if you know how to manipulate data and track people through their interactions with computers everyday. The story was about a super computer that could match compatible couples with 95% accuracy. Some couples matched in every point and were called super-couples because they matched with 100% accuracy as the perfect match for each other. The book said that most couples are about a 35-50% match in the real world. However, in the book, the super-couples started committing suicide, even though friends and family said they were perfectly happy. Getting to the bottom of why was very interesting. I will re-read this book in a couple of years it was so good.
