Reader asks is a counted number: parsed reader requests — from Goodreads and Amazon reviews and Q&A, Reddit and BookTok — in which a reader writing about this lane named both tropes in the same request. 1,840,565 reader signals sit behind it. Titles carrying both is counted the same way over published titles tagged trope by trope: 11,638 distinct titles, 67,875 trope tags. Neither number is modelled, sampled or estimated.
Two things to be straight about. The supply count is registry-wide, not lane-scoped — our demand data and our title tagging use different subgenre vocabularies, and rather than fake a join we count titles carrying both tropes anywhere in the tagged registry. And a pairing is only listed when both of its tropes carry at least five tagged titles on their own (the two figures are printed under each pairing), so a zero in the “carrying both” column means the pairing really is unwritten in what we have tagged, not that we simply never tagged the trope.
The verdict column is a rule, printed here so you can apply it yourself: ten or more asks per published title is an open gap; three to ten is thin on the shelf; below three is well served; and a pairing readers ask for that no tagged title in the lane carries at all is called out as such. Pairings with fewer than three asks are not listed — too few to mean anything.
What it is not. It is not a sales forecast and it is not advice to write anything. A gap can be a gap because readers ask and nobody delivers, or because the pairing does not work. That judgement is yours; the counting is ours. Counted 2026-08-22 and restated whenever the corpus is recounted — the raw JSON behind any lane is one query string away.
