Our data cannot show that dark romance is oversaturated. On the reader side, dark romance has stayed between 2.8% and 4.4% of romance demand signals in every quarter since 2024, which does not look like readers moving on, though its share has eased a little in Goodreads reviews. Oversaturation means too many books for those readers, and we do not count every book on the shelf, so we cannot give you a saturation number.
It means the supply of books has outrun what readers want. That takes two measurements: how many books there are, and how much readers want them. Tropesmith's counts cover the second only in part: they come from what readers write in reviews, comments and posts. For the first it tracks bestseller charts and a registry of tagged titles, not every book on Amazon. Anyone who gives you a flat yes or no is guessing.
A demand signal is one specific thing a reader asked for or praised in a review, comment or post. The table shows what share of the romance demand signals posted in each quarter mention dark romance as a main or secondary tag.
| Quarter posted | Romance demand signals | All sources | Goodreads reviews | BookTok comments |
|---|---|---|---|---|
| 2024 Q1 | 18,714 | 2.8% | 2.6% | 5.8% |
| 2024 Q2 | 20,034 | 3.1% | 2.9% | 5.3% |
| 2024 Q3 | 22,031 | 3.2% | 2.9% | 7.4% |
| 2024 Q4 | 23,356 | 3.5% | 3.0% | 9.7% |
| 2025 Q1 | 28,803 | 3.7% | 3.2% | 9.9% |
| 2025 Q2 | 31,538 | 3.5% | 3.2% | 6.6% |
| 2025 Q3 | 36,659 | 3.8% | 3.4% | 7.9% |
| 2025 Q4 | 41,033 | 4.4% | 3.8% | 9.2% |
| 2026 Q1 | 58,480 | 3.9% | 3.2% | 9.5% |
| 2026 Q2 | 163,466 | 3.5% | 3.1% | 7.0% |
| 2026 Q3 | 216,012 | 3.7% | 3.1% | 8.5% |
Across all sources the share ranged from 2.8% to 4.4% and sat between 3.5% and 3.9% in 2026. Within Goodreads reviews alone it rose from 2.6% to a peak of 3.8% in the last quarter of 2025 and has eased to 3.1% in the third quarter of 2026. BookTok comments mention dark romance at a much higher rate, between about 5% and 10% of their romance signals, and are a larger slice of the corpus than in 2024 (7% of romance signals then, 11% in 2026 Q3), which helps keep the all-source figure steadier than the review figure. Tropesmith reads reviews some time after they are posted, so the newest quarter is the least complete. Treat this as a rough guide, not a trend line.
Counted 2026-10-09 06:25 UTC by direct query against the Tropesmith corpus. "Romance demand signals" means signals assigned to a romance subgenre. Compare the shares, not the raw counts: romance demand signals per quarter grew from about 19,000 to more than 215,000 over this period. Signals with no posting date (almost all Amazon reviews), signals not assigned to a subgenre and the partial current quarter are left out. How we count.

Build my Map → See a real sample Map first →Readers still mention it. Across all sources, dark romance appeared in 3.5% to 3.9% of romance demand signals in each quarter of 2026 so far, though its share in Goodreads reviews alone has eased since late 2025. Mentions are not sales, so use them to compare tropes with each other, not to forecast earnings.
Crowded and closed are different things. Our counts cover the reader side only, so check the supply side yourself: the market snapshot shows how many new titles recently entered the lane's bestseller charts. If new titles keep entering, new books are still finding readers. That is a sign, not proof.
Popular means many readers want it. Oversaturated means there are more books than those readers can absorb. A lane can be both popular and crowded, and the useful question for your book is whether your particular trope mix is crowded.
