Data note: every figure here comes from TropeSmith, our sister company. TropeSmith has analyzed 2.59 million demand signals: specific things readers asked for or praised in reviews, comments and posts (counted October 7, 2026). 12,771 of them mention Age Gap, and 43% of those are tagged underserved or novel by TropeSmith’s classifier. The classifier reads each signal on its own and is never shown what is on the shelf, so treat the tag as a pointer to check comp titles, not proof that no book answers it.
TropeSmith counted 12,771 demand signals that mention Age Gap. Most “best trope” lists run on vibes. Ours runs on counts.
