Averaged engineered signals

Every measure here is the mean across this author's catalog — the characteristic way their books work the immersion engine, on the same axes the catalog scores every title.

Avg heat rating
3/5791,821 words across 4 books — 2,778 pages
Anticipation Ratio
79Share of page-time spent on buildup and tension rather than payoff. High values mean the book sells the wait, not the moment.
Explicit Density
0.5avg explicit scenes / 100 pages
POV Immersion
89How strongly the narration collapses the gap between reader and protagonist, peaking with first-person, reader-insert voice.
Parasocial Index
80The "book boyfriend" pull: how hard the text works to form a one-sided attachment to a love interest.
Serialization
79Cliffhanger and serial-loop intensity — the compulsion to start the next chapter or installment.
Escalation Slope
59How steeply intensity ramps across the arc. A steep slope is the tolerance signal: each payoff has to outdo the last.
Across 4 titles, this author scores 85/100 on formula consistency — how little their engineered signals vary from book to book. A high score reads as a repeatable production formula rather than a wide creative range.

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).
