First, it's worth reading, but perhaps only if your technically inclined.
Second, this is a techno-thriller. But it's _very_ very heavy on the tech, sometimes to the determent of the story. If you can keep working through those parts it's worth reading.
Third, Why, o why, does every male hero have to morph into Rambo? Honestly it was the wife and her fathers relationship that kept me interested, and less the husband.
Forth, that last minute left hook into mysticism? Yeah, we could have skiped that or at least tied it in earlier so it seemed planned. I don't mind mysticism in my books, but please make them a part of the universe and not a deus ex machina thrown in at the last minute.
