You take a story and explain the entire thing with only a couple paragraphs, and you don't want to give away any special details that way a person can know a little about the book and want to read it. Like a "A dog and His Ball" is about a lost dog who doesn't have a family and finds an old ball to play with. You would put this on the back of a book and then people would be drawn to read this book. ( I just made something up so it may not make sense sorry.)
I'm not really sure I understand what you are asking, but I tried to answer the best I could, please let me know if this isn't what you meant.
I would say a hero is someone who stands out from the crowd and exceeds expectations to change the world. A hero is someone who perseveres to help society. During these dark days, for sure, all nurses, doctors, paramedics, firefighters are defined as heroes. They fight to save a life. To save a life that is crucial to its surroundings and community. With all their might, these heroes push and push and push the dark door away from the way to hopefully see the light that we are all waiting for.
Isn't it hug?
That is the best I could come up with
