The threshold as structural core
Rites of passage fiction is organized around a threshold: a point of no return after which the protagonist's relationship to the world, to others, and to themselves is permanently changed. The threshold is not an event; it is a before and after. Writing the threshold well requires knowing precisely what it is — not the event that triggers it but the specific change in the protagonist's understanding or capacity or relationship to innocence that the event produces. The story's structure should move the protagonist toward the threshold through a series of experiences that prepare them for crossing it, place them at the threshold in a moment of maximum clarity, and then follow them into the changed territory on the other side.
