Question: 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.

Answer: Positive

Question: I've heard it said that this is Kerouac's greatest novel. I still say that honor is held by On the Road, but this book is just as good. And it is his most spiritual novel. Kerouac combines his talent at writing with his philosophy of life and what you have is a powerful tool to enlightenment. This book should be read on at least two levels, as a work of great literature and as a theological tool. I can't recommend it enough.

Answer:
Positive
