Query: Very disappointing

Having always enjoyed Robin Cook's books, I was "shocked" and very disappointed with his latest. If on any bestseller list it will be solely because it WAS written by Robin Cook and certainly not due to it's own merit. The characters are shallow and their relationships are unbelievable. While the topic seems to be taken from today's newpaper headlines, the story itself is just not up to it. Unfortunately, after a book like this, readers may distrust the next book a writer publishes.....even if that writer is Robin Cook.
