Best Marriage of Convenience Romantasy Books

Marriage of convenience works because it cheats. It hands two people all the proximity, domesticity, and enforced intimacy of a relationship — the shared beds, the overheard nightmares, the accidental tenderness — while both parties are still technically allowed to keep their guard up. The tension comes from watching that permission slip expire. Readers return to this trope not for the wedding but for the exact moment the protagonist realizes the contract has stopped protecting her from her own feelings. Done well, it's one of the most psychologically rich setups in romantasy: the power imbalance is built in, the denial is structurally justified, and the emotional collapse when it finally comes feels utterly earned.

Bride by Ali Hazelwood transplants the trope into a monster romance — a vampire-werewolf political alliance sealed through marriage — and then quietly makes it about learning to trust someone whose entire world is engineered to exclude you. The slow build is patient in a way that pays off hard. Radiance by Grace Draven does something rarer: both the hero and heroine are considered ugly by their own cultures, so the mutual arrangement comes without the usual power fantasy, and the tenderness that grows between them has an almost uncomfortably real warmth to it. Serpent & Dove by Shelby Mahurin sets the marriage inside an active witch hunt, which means the stakes of the ruse unraveling are lethal, not just emotionally costly — it keeps the pacing tight in a way more languid entries in this trope sometimes lack.
