How We Label Books

Burn speed, heat and ending are separate labels. Burn speed describes how long the relationship takes to resolve (gentle, slow, very slow or series-long); heat describes on-page intimacy (sweet, closed door, open door, explicit, extra spicy); ending distinguishes HEA, HFN, bittersweet, tragic and series outcomes.
