I'm going through a bit of a cold northern phase at the moment! What about:
Michelle Paver - Dark Matter (psychological mystery/thriller on arctic research trip)
Steff Penney - Under a Pole Star (more arctic exploration this time in Greenland in 1890s, but in fact quite an (ahem) steamy love story too)
I also loved another of Steff Penney's previous books - Tenderness of Wolves - lots of trekking through snow in remote American West
Kim Leine - The Prophets of Eternal Fjord (another one set in Greenland in the 1790s; hard to describe; Not that much about nature to be honest, more about religion, the human condition, and the grimness of life in a Danish colony; I've just finished it and thought it was great but it's a bit gruelling. Anyone else read it?)
Hannah Kent - Burial Rites (1820s Iceland; woman convicted of murder; lots of details about grimness of life in Iceland)
Lionel Davidson - Kolymsky Heights - totally different to the preceeding recomendations. Modern-ish spy thiller set in deepest Siberia. Absolute page turner.
