Second in the Temperance Brennan series by Kathy Reichs...
It would appear that I read the first book in the series about two years ago. This one didn't grab me quite as much as the first one did.
It felt a little more like just plot. Go here, find that, connect this, go there, find thing two, connect that to thing one.... repeat. There was a mystery and deaths to prevent and all that, but for whatever reason I just didn't care that much.
Maybe it was that the coincidence factor was really high. There's this group that just happens to recruit Tempe's sister in Texas and want her to go with them to a specific place in Canada (near Tempe's place of employment there of course) and they just happen to have another part of their group active where she lives in North Carolina. It was all just a little too neat for me.
