If you enjoyed Coben's Myron Bolitar novels and are expecting great things from this novel, don't read it! I love the Myron series and I have never been more disappointed in a book as I was in this one.
One of the things that I enjoyed so much about the Myron books was the witty dialogue and likeable characters (like Win and Esperanza). In this book, Coben tried to be too serious so the dialogue was very sappy and unoriginal (the same goes for the characters). The readers are also treated to the main character's constant running social commentary on the lower class and how some criminals are just misunderstood. "Don't judge a book by its cover" stuff.
Another problem that made me uninterested in all the characters was the fact that the good guys are ridiculously good (the main character, his wife, and his sister ALL work for the poor), the bad guys are ridiculously evil (the evil billionaire and his unbelieveably sadistic hitman), and, in classic Harlan Coben style, the cops investigating are all dumb, bull-headed creeps who, if they were any worse, would be wearing swastikas on their arms. Oh yeah, and I forgot the "look at me, I'm so politically correct" lesbian couple, the typical boisterous defense attorney, and the drug dealer with the heart of gold.
If you're a Harlan Coben fan, stick to his Myron Bolitar novels. This is like a Myron book without any witty dialogue, likeable characters, or interesting plot developments. Coben's best work is clearly behind him unless he resurrects Myron, I don't think it's going to get better.
