The Cobra Event

I am reading a book by Richard Preston that is called The Cobra Event. I am about one-third of the way done with it so far. The book is like a scary medical mystery. There is a chain of unsolved deaths that are all related but no one can figure out how. But, yet they know that there are about to be more deaths...Richard Preston is the author of a bestseller: The Hot Zone. If you like scary books that you can't put down, then these books are calling your name...
