This book is really not a story of two travelers but a self-insertion of how the authors view post-nuclear war US.
Neither is sympathetic. Whitley, who’s hiding in a church with his family describes how two children lost both of their parents but “I never learned what became of the Parker girls.” Which shows just how self-absorbed he is. His wife isn’t very believable either. I mean there was a nuclear attack and she thought of her son but she just so happens to think that she should grab food just in case?
We also hear the refrain, “I/We never learned what happened to ???” Then why bring them into the story?
Since I didn’t care about the two authors I didn’t care about their tale either.
