I've read many books since my last post. Theses are the latest, and well-worth reading:
The Light Between Oceans, ML Stedman and
The Dog Stars, Peter Heller
These books are very different, but both deal with with tragic and profound loss as the background for the decisions that people make about their lives. Each is set in a remote area. The Light Between Ocean takes place in 1920's Australia, most of it at a remote lighthouse. The Dog Stars is set in a post-pandemic and sparsely populated US, a short time into the future. Read them both.
