Retcon (short for "retroactive continuity") as a book-category describes works that deliberately revise, reinterpret, or overwrite previously established events, characters, or worldbuilding within a fictional universe. These books center on revelations, new perspectives, time-travel or memory-altering devices, or new authorship that changes what readers believed to be true—either to fix inconsistencies, modernize themes, deepen mysteries, or create surprising twists that reframe the narrative. Retcon novels can appear in any genre—fantasy, science fiction, mystery, or literary fiction—and often explore the emotional and ethical consequences of rewriting the past, playing with ideas of truth, memory, and legacy. They appeal to readers who enjoy puzzles, meta-commentary on storytelling, and the tension between nostalgia for the original canon and curiosity about fresh directions.
