Shock Wave

I really enjoyed this series, though I probably would have had a bit more suspense if I hadn't read this last out of the series and known one of the people was trustworthy because of their having a starring role in the last book. I loved how vivid each of the characters were and how the culprit fit so well into everyday life and was hard to spot until the end. Also, the side story with what happened to Barbara kept me flipping the pages to see if she could possibly survive.

Fair warning: earthquakes while in buildings and subterranean passages. Not for the severely claustrophobic.
