Content signature
The content this author's catalog leans into — first-pass lexical matches across 3 books.
Share of page-time spent on buildup and tension rather than payoff. High values mean the book sells the wait, not the moment.
How strongly the narration collapses the gap between reader and protagonist, peaking with first-person, reader-insert voice.
The "book boyfriend" pull: how hard the text works to form a one-sided attachment to a love interest.
Cliffhanger and serial-loop intensity — the compulsion to start the next chapter or installment.
How steeply intensity ramps across the arc. A steep slope is the tolerance signal: each payoff has to outdo the last.
