So, the title if this small novel as i recall it is “Death Flees Me”. However, I cant find it under this name so i am probably mis-remembering.

The novel was about the End Times, written from the point of view of a non-believer. As I remember it, it was not very religious at all. It simply played out the story of his wife and friends disappearing one day. I recall nothing else about the story. It was short, a very thin book.
