Sinful Oath
by Kira Cole & Callie Stevens · Independent · 2024
An arranged-marriage bratva romance that engineers attachment by trapping a defiant heroine and an emotionally guarded boss in forced proximity, then alternating their first-person present-tense confessions so the reader feels each crack in his armor and her falling in real time. A late surprise-pregnancy reveal converts slow-burn tension into a high-stakes hook, and a next-book teaser closes the loop to funnel readers onward.

Location
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.
