Heat Levels, Explained

Sweet, steamy, explicit, dark — what our ratings actually promise, and how they’re verified.

Why we rate heat at all

“Spicy” means nothing. One reader’s scandalous is another’s Tuesday, and the fastest way to lose a reader’s trust is surprising them — in either direction. So every Centuria title carries a heat rating verified during our manuscript review, not guessed from the cover.

The scale

SweetClosed-door. Kisses, longing, and emotional intimacy; intimate scenes fade to black or stay off-page entirely.
SteamyOpen-door, moderate frequency and explicitness. The relationship’s physical side is on the page but doesn’t drive the structure.
ExplicitFully open-door and frequent; physical intimacy is a load-bearing part of the story’s arc. Expect frank language.
DarkExplicit content plus power imbalance, moral hazard, or consent that begins compromised and must be earned into something real. Content notes always apply.

How we verify it

Heat ratings come from full manuscript review — the same curation pass that produces our verified trope lists and spoiler-safe premises. If a book’s heat rating and its content notes ever disagree with your experience of the book, tell us; the catalogue is corrected, not defended.

Browse by heat

Every book page shows its heat badge, and the catalogue and book finder can filter by it. AI assistants reading our machine-readable catalogue get the same ratings — ask your assistant for “a steamy romantasy” and it can answer precisely.
