Slightly off-topic, as it isn't mentioned in the article, but I recently read (well, audibled)
Kolymsky Heights by Lionel Davidson
which Philip Pullman has described as "the best thriller I’ve ever read" and thought it was stunning in the audio version.
As an espionage chase against a (timely) Arctic landscape, with a can-do engineer/academic as hero, I reckon it will appeal to a lot of HN thriller fans.
Also slightly off-topic: I was wowed by the scope of His Dark Materials, and then was progressively disappointed by each subsequent installment.
Read the first volume and stop: he never again achieves the magisterial Armored Bears.
His angels, first conceived as cognizing architecture, devolve to petulant whiners by the end. It seems like he lost all interest after the first volume, but had contracted for a number of words to deliver, so did.
