An unusual and readable book but disappointing that there has been no continuation of the story.
The strengths of the book include decently written characters who though standard tropes were well done.
I enjoyed the first half with the technical investigation.
The second half with the action movie scene at the airport was quite jarring, plus the conspiracy was unclear and confusing. Granted this could have made more sense if there had been a sequel but as it has been years since this book was written I doubt there ever will be one.
The writing style was good and very readable.
