Act as an expert literary critic and novelist. Outline the plot structure for a literary fiction novel that utilizes a fragmented, non-linear timeline across three distinct decades (1980s, 2000s, 2020s). The narrative must slowly reveal a single traumatic event that connects all three timelines, but the truth of the event should only be fully understood in the final chapter. Explain how you will manage pacing, character voice consistency across ages, and the use of narrative anchors (recurring symbols or phrases) to guide the reader through temporal shifts without explicit chapter headers stating the date.
