Exciting enough with plenty of Ben Hope action, but a somewhat different take on things in this book. A very chance meeting sees Ben on the lookout for someone who appears to have committed suicide, but whose twin brother dos not believe that to be the case. The premise behind the book centres on Global Green issues, with those apparently protecting the planet from global warming having other ideas. There is a great deal of exposition of such global issues, obviously well-researched by Scott Mariani, although I felt that some of it was a little bit of a stretch. However, I am not an expert, and it did make for a good read. There is a great deal of action in the book, but it did not quite hold my attention as others have. That may have been too much factual detail detracting from the pace of the story. Perhaps the next in the series will show Ben back to his best.
