This is a fast paced thriller/ mystery. Really good and interesting. Makes one think "What if".

I have read four of Rollins' books, two of which I gave five stars, but since I almost stopped reading this book at most it only gets two stars. It is one of the few books that I laid down several times and wondered if it was worth finishing as I didn't care how it ended.

I did a lot of skipping past the code-breaking details. Here is part of a review by Dr. J. "Dr. J" (Virginia) posted on April 28, 2007 that says it all, "What would you tell me if I was trying to find some socks in my 10 year old's room (a feat to itself), and I told you that because I found a drawing of a cat on his desk, and cats have 4 legs, 2 ears, and 1 tail, that this means that there are 7 paces from the desk to the socks somehow. But wait, the cat was pointing north, so it means that I must perhaps take the fact that cats are said to have 9 lives, and take the difference, so that confirms that there are 2 socks in a pair missing due north in the room! Amazing, isn't it?"

If you can suspend your disbelief and skip pass the dribble, Rollins can tell a good story about a plot that leaves a lot to be desired.

If you want a fun, historically interesting, fast read - this is it. I liked the book but was at times thinking it was a bit ridiculous. The end was a bit of a dud for me too. Overall, I liked the history and science in the book - all of which can be further researched. And, I liked the main characters. There is a clunky mini-romantic element which I am not sure why it was included. There are some over the top sequences and escapes too. But you read these books for what they are - escapist fun! Suspend disbelief for a while and enjoy. I am looking forward to reading the other Sigma Force books.

Map of Bones is a fast paced thrill ride. I loved it. The book is a little too long, but all in all, I couldn't get enough. This is the second book in the Sigma series. The first book, Sandstorm, is not as good, and most of the central characters are introduced in Map of Bones and not in the first book.

I just completed reading this book and it is a great read. I would have read it much faster if my freetime had permitted. I never wanted to put the book down. I can't wait to read the books that the author used to gather the facts used in this book! I will not tell you about the story itself. You will have to read and see for yourself...
