The President is Missing by James Patterson and Bill Clinton

The President is Missing by James Patterson and Bill Clinton,  513 pages

I was apprehensive about reading this book and knew nothing of the plot before I read it.  For a James Patterson novel, I found it an enjoyable read.  Maybe, because Bill Clinton was the coauthor.  I found this book really relevant in today's current world situation.  In this book, the President goes missing.  But, for good reason.  A virus is about to be unleashed on all the computers in the United States, taking out all the Pentagon's computers.  Can the President stop it before it destroys the United States?
