This book must have been written by someone who wanted to use an entire dictionary of jargon, regardless of the effect it would have on the book itself. While I admire that it was used correctly, it just seemed highly unlikely. I liked the idea of the backstory interspersed with the main story and finally merging. It was very clever. For that matter, I liked the plot. It was very unique and imaginative, as well as believable.
However the characters were overdone. The main character was too impossibly overwrought. He isn't just ex-military and hard, but he has ALL the characteristics of being ex-military and tough. You don't go through a page or two before you are reminded just how tough he really is. After a while it became tediously testosterone-laden. (Arggh! Let's drink a beer and eat a cheeseburger and forget about all that fancy wine and using a knife and fork!)
The ancillary characters are larger than life too. The PI's associate is (named Dagmar,) and is opulent in every way possible. It seems that every character is a stereotype of the person he/she represents. Additionally, there were too many of them. Do I really have to remember the names of the used car lot husband and wife? There are lots of characters and they clog the book and provide side stories which are occasionally enjoyable. Still, I tired of thinking, "Who is this person again?" so often when he or she just wasn't important.
It was a good book to read when you just want to lose yourself in a fun mystery. Like I said, I never guessed how it was going to turn out...and the jargon will make you laugh.
I did, however, not see what was going to happen until it was revealed. In that respect, it was a great book.
