Romantasy Heat Index
A friendly cheat sheet for talking about romantasy spice without whispering into your sleeve at the bookstore.
Romantasy heat is allowed to be fun to describe. No lab coat. No moral sermon. No tiny panic voice saying, “There is kissing,” while your aunt browses nearby. Use this index to talk about spice clearly, warmly, and without making the book feel like evidence.
The 3-Part Heat Check
Use these three markers when you describe a romantasy book:
- Door: How much is shown on the page?
- Delay: How long does the book make you wait?
- Damage: What does the romance change?
That last one matters. If one kiss makes a prince forget a treaty, we need to know.
Level 1: Closed-Door Longing
Use this when the heat is mostly yearning, glances, almost-touches, and emotional wreckage in formal clothing.
Good phrases:
- “Low on-page spice, high romantic tension.”
- “Lots of longing, fade-to-black intimacy.”
- “More hand-brushing than mattress logistics.”
Best for readers who want the ache, the devotion, the forehead touch, the scene where someone says “stay” and everyone in the room needs a chair.
Level 2: Slow Burn With Smoke
Use this when the book takes its sweet time. The romance simmers. People deny obvious feelings with the confidence of fools near candles.
Good phrases:
- “Slow burn with eventual payoff.”
- “Tension first, spice later.”
- “They suffer beautifully before making choices.”
Helpful note: slow burn describes timing, not spice level. A slow burn can stay closed-door, or it can arrive at the door with a battering ram. Be specific. Future readers deserve warning. And snacks.
Level 3: Open Flame
Use this when intimacy happens on the page and the book lets you see the details.
Good phrases:
- “Open-door romance.”
- “Moderate to high on-page spice.”
- “The intimacy is part of the relationship, not a quick curtain drop.”
This is the level where the romance stops politely standing in the hallway. Fine. Everybody remain calm. The dragon is probably also involved somehow, emotionally if not physically.
Level 4: Kingdom-Delaying Decisions
Use this when the heat is high and the romance starts interfering with urgent public business.
Good phrases:
- “High heat, high consequences.”
- “Spice plus plot fallout.”
- “They should be solving the curse, but feelings have seized the schedule.”
This is for books where desire changes alliances, ruins plans, delays coronations, complicates prophecy, or makes one immortal person dramatically useless for several chapters.
