As a person who is sometimes plot impaired, I've often tried to grok the essence of plot. Yesterday my fourteen-year-old niece Sage was over to the house. She was telling me all about her latest favorite YA novel. She spent a long time explaining the set up, introducing me to the protaganist, describing her family, etc. Then she said, "Then a lot of bad, weird things go down and they have to figure it out." I had to laugh. She had just summerized three fourths of the book in one sentence-- and pretty much summed up plot in general, don't you think?
Hope your writing is going well!
