I've really enjoyed many of Jeffery Deaver's books, he is one of my favorite authors. However, this book was a HUGE disappointment! If written by anyone else I would have quit after 50 pages. I find it hard to believe Jeffery Deaver wrote such a boring book.I gave it one star because Deaver has always rated 5 stars with his other books,in my opinion, until this flop.
