I don't know why I keep reading Patricia Cornwell's books!...Probably because I started reading from the first Kay Scarpetta book, & you can get hooked. The first Scarpetta books were excellent, the kind of books you read in one sitting. But "Point of Origin", in my opinion, was nothing like the other books. The ending depressed me- not that the author had to chose a happy ending. But one of the most interesting characters in the series is now dead...Apart from that, I found it boring that Cornwell uses the same villain over & over again. Even after being disappointed with this book though, I think I'll still read the next one! Old habits are hard to break.
