Act as a Literary Author. Create a detailed plot outline for a literary fiction novel that utilizes a recursive timeline structure (similar to 'Time's Arrow' or 'Remainder'). The story must be told backwards, ending at the beginning of the event that changed the protagonist's life. Define the inciting incident (which occurs at the end of the text), the climax, and the resolution. Ensure that the causality remains logical despite the reverse chronological flow, and explain how this structure enhances the theme of irreversible regret.
