There is a style of nonfiction that I have seen called journalistic nonfiction that is all about telling a good story that happens to be true. There are also introduction books to obscure topics aimed at general readers.

Books like And the Band Played On by Shilts or Endurance by Lansing tell a compelling story.

The Man Who Mistook his wife for a hat is an introduction to neurological diseases through interesting anecdotes.

Stolen Focus by Johan Hari is an expose of Social media impact on attention span.
