3. First Major Turning Point
By now, your plot is picking up steam, and because of Box 2, the reader is invested in the ride. Time to throw a curve ball. This turning point can be either a positive event for your protagonist, or a negative one, but it should lay the groundwork for the negative turning point in Box 6. There is a reason these boxes are touching one another; they interrelate. For example, Box 3 may introduce the motivation of the antagonist, which then justifies the events in Box 6.
