I see this book has gotten quite a few negative reviews on this forum, but I really liked it. This, along with Jackdaws, I think are my two favorites of Follett's. I can't comment on either the realism of the earthquake scenario or the realism of the FBI office, but only experts will nitpick at that anyway. This was an exciting page turner with interesting characters & especially a villain you love to hate -- the evil psychopathic old hippie, Ricky aka Priest. If you are a Follett fan, definitely give this one a chance.
