Query: Really enjoyed! From a diehard Harlan Coben fan!

I had seen a number of negative reviews about this book and had subsequently not purchased it myself, even though I have read every other Harlan Coben book including his Mickey Bolitar books. But then a neighbor mentioned that she had bought this book, was reading it, and couldn't put it down! So I bought it and can say that I agree 100%. I read this book in about 4 days of my commute back and forth to work, the book is about 470 pages, and I am not a fast reader!I'm a big Myron Bolitar fan, and this book is not as good as some of his Bolitar books, but it's definitely worth the price of admission and a good read on its own.
