Like all of her Scarpetta mystery novels, Patricia Cornwell has proven again that she must have been one dynamite of a Coroner when she was practicing. She has a wealth of information in her books and it is so interesting to follow as she progresses to solving the mystery. I've never enjoyed reading as much as when I pick up a Cornwell novel.

I ordered this DVD & several others as presents. They all arrived in good shape & on time for Christmas morning.

Foundation is a great book to read. The Foundation trilogy is a great series to read. That being said, there are little elements within the story that date some of the points of reference Asimov ascribes to his characters, but it's actually charming to read the references to 'atomics', etc. Asimov is a master at story-telling, and this series certainly helped to cement his reputation.
