Map of Bones wasn't bad. I had been hoping for more of an early Tom Clancy type of read, but this was a little thin on most counts.
There was a lot of exposition, feeling as if one character telling the others the whole history of the world at times. It certainly shows off that the author did a lot of research. I found it all a bit complicated and more than once it felt like a bit of a slog to get through things and get down to the action.
The characters were okay - generic techno-thriller types with an interesting quirk or two that I thought could have been explored a little more. There was a bit of a romance as there often is in this type of book, but it never hooked me. I actually wanted to know more about what was going on with a couple of the secondary characters more than the main couple.
There were some interesting twists and turns and one HELLUVA twist that managed to catch me completely by surprise. I wanted more about the motivations though.
All in all, this was a pleasant read and should the others in the series (yes, this is apparently the first of the Sigma Force books), go on sale for a reasonable price, I'll pick them up. I wonder if they'll deal with the same characters at all? Hmm...
