The Cutting Edge is the latest novel in the Lincoln Rhyme series, which is one of my favorite series. For those who don't know, Lincoln Rhyme is a criminalist who is also a quadriplegic. He's one of the best in the world at analyzing crime scenes but, since he became disabled, he relies on others to be do the physical examination of the scenes. This novel can be read without reading any of the earlier ones (although I think reading the series in at least rough order would be more enjoyable).
As in all of the books in the series, Rhyme is called in to help on a serial murder case. Relatively early on, we learn that the villain, who is crazy, is killing engaged couples because of their diamond rings - he thinks making diamonds is horrible.
Also as in all the books, there are twists and twists until the final page. Deaver is a master of fitting together all the pieces of his plots so that they make sense. However, I think he takes it one step too far in this book, so it's not my favorite of the series. But it's still very good and will keep you turning the pages.
NOTE: There are scenes of extreme violence in this book. If that turns you off, you shouldn't read it.
