Story Plot is an excellent overview of various plot structures.
I appreciated the author’s input on how different structures relate, their similarities and differences. I also rather enjoyed the addition of Propp’s folktale morphology and Kishotenketsu, two unique plot structures that I’d never heard of.
The comparison to modern stories is helpful in solidifying the concepts, and the short and easy to read format makes it easy to breeze through the content. You can choose to pursue further studies of your preferred structures via the references mentioned in the book, or use the concepts outright.
Story Plot is a great reference book for any storyteller.
