I got this softcover at Toadstool Books in Nashua. It's about a group of people in a Swiss hotel, stranded there after a nuclear war has devastated the planet. As their own survival becomes more and more of an issue, one character remains focused on finding the truth behind the mysterious death of a young girl, a death that must have occurred at about the same time as the nuclear war... [The premise - people trying to cope with the end of the world as they know it - reminded me of The Last Policeman
, though that has a different twist: the world is threatened by an approaching asteroid, so while the only immediate danger is that caused by other humans and their reactions, the end game makes people reconsider what they want their final months to consist of.]
The focus on the narrator's viewpoint and the limited scope of the hotel makes this something of a "quiet catastrophe" - though it's not without examples of tragedy, stress, and horrific acts. Those tend to be in the background, though, and if it's possible for an apocalyptic tale to have a hopeful conclusion one could say that this one does - though it doesn't tie up all the loose ends, by any means.
