This wasn't as good as Mortal Fear, but still enjoyable. The first 12 pages hook you, but then the book slows down until about midway. Half way through, the book picks up speed and hooks you again. After reading two Robin Cook novels in a row, his books sounded formulaic, so I don't recommend reading his novels back to back if you're easily annoyed by formulaic writing. I still love his novels and plan to read more, but now I need something else. If you're in a reading rut, a medical thriller is a great choice.
