Serialization
72Cliffhanger and serial-loop intensity — the compulsion to start the next chapter or installment.

Estimated. Every signal on this page is an analytical estimate from automated text sampling — directional, not an exact measurement — and the arc curves are illustrative shapes, not chapter-by-chapter readings.

Anticipation Ratio
Share of page-time spent on buildup and tension rather than payoff. High values mean the book sells the wait, not the moment.
Explicit Density
Explicit scenes per 100 pages — how concentrated the payoff is across the length of the book.
POV Immersion
How strongly the narration collapses the gap between reader and protagonist, peaking with first-person, reader-insert voice.
Parasocial Index
The "book boyfriend" pull: how hard the text works to form a one-sided attachment to a love interest.
Serialization
Cliffhanger and serial-loop intensity — the compulsion to start the next chapter or installment.
Escalation Slope
How steeply intensity ramps across the arc. A steep slope is the tolerance signal: each payoff has to outdo the last.

An analytical project. Truth in Romance examines and quantifies how explicit-romance fiction is constructed — including the explicit passages themselves. It contains adult content and is intended for readers 18 and over. The books in the catalog are real published works; their titles and contents are discussed here for research, commentary, and criticism. The per-book signal scores, arc shapes, and tag weights are the project’s own analytical estimates from automated text sampling — directional, not exact measurements, and not the publishers’ figures. Industry figures are attributed to published industry research (Circana and similar).
