I'm reading the book 179 Ways to Save a Novel by Peter Selgin. Selgin writes, "Remember that there are really only two plots: Plot A, where a character is routinely unhappy and suddenly seizes an opportunity for happiness, and Plot B, where a character is routinely happy but some circumstance or irritant destroys or undermines his happiness, and he must act to reinstate his status quo. The solution to plot is to make sure you are dealing with one of these situations."
Just for grins, I took a look at my work in progress (the revision/rewrite of a finished novel). I feel Plot B is the closest because the story evolves out of something distressing that happens to turn the character's mostly acceptable life upside down. At the same time, the character was not entirely happy with her life before the upsetting incident, and is open to seizing a new opportunity for happiness. She wants to "reinstate the status quo" in some respects but also would welcome change.
What do you think of Selgin's two plots? Would you identify your current WIP as Plot A or Plot B? Why?
