Query: The Laws of Invisible Things

Without going into elaborate detail, I find it necessary to report that this book is NOT one I would recommend to anyone. The protagonist Dr. Grant blunders about in a plotline that is so weak that Huyler fails to deliver a conclusion. This book goes absolutely nowhere, and I regret the time I invested in reading it through to the end. The blurbs promise a medical thriller like The Hot Zone or Darwin's Radio, but Huyler's novel is a paltry wanna-be. A doctor who writes a book can throw in a lot of medical jargon, but what he needs is a solid plot -- not one based on "invisible things!"
