Woods and Trees in the North?

I just caught the last few minutes of a programme on Radio 4 which sounded interesting, Woods and Trees - Iceland and the Scottish Islands. I went to Listen Again, to find out what they could say about trees in the largely treeless landscapes of Iceland and the Scottish islands! It turned out to be a composite programme, one bit about woods and trees and the other bit about Iceland and the Scottish Islands. Pity, it would have been interesting to hear a bit more about trees in these landscapes.
The second part of the programme was an interview with Sarah Moss, whose book Cold Earth I read a while ago. It's a thriller set in an archaeological dig in Greenland, with lots of strange happenings, in many ways not unlike the atmosphere conjured up by the Icelandic sagas that are set in Greenland. The archaeology bits are not especially credible, but it's an effective story all the same.
It turns out that Sarah Moss has lived in Iceland (which was what she was being interviewed about) and is currently writing a book about it. On following her up I see she just has a new novel out, Night Waking, set in the Hebrides, and on the programme she recalled her childhood holidays in Orkney. She is clearly a lady who likes all the right places! I shall check out this new novel and see what I think.
