Where DVC is ancient history and Angels and Demons os more recent history, this one is futuristic science that might be today, cloaked in a mystery thriller form.
It might be a silly reason to like the book - but the evocatively described atmosphere of arctic dark night of a winter and cold icy polar surroundings that was the background of the thrills of scientific discoveries and the terrors and murders gave it a special something - perhaps as others might like the new version of Hitchcock's Man Who Knew Too Much for the Algiers desert beginning for atmosphere and the music that is woven through, rather than the original that begins with a rifle shooting competition in the beginning and the throughout placid stoic bearing of the English aristocratic couple in face of a daughter kidnapped and in danger.
