A treaty, a crown, a debt — anything but love. Then they have to live with it. These are the romantasy books that turn a contract into the slowest, most satisfying burn in the genre.

Why the Contract Version Hits Hardest
Forced proximity traps people in a room. A marriage of convenience traps them in a role.
That's the upgrade. They're not just stuck near each other — they have to perform intimacy in public, share a title, present a united front to a court that's watching. Every false gesture in front of an audience becomes a real one in private, and neither of them can call it what it is without admitting the arrangement stopped being an arrangement.
The trope's whole power is the gap between the performance and the truth, and how long an author can keep that gap open.
Ranked by How Well They Sustain the Tension
1. The Bridge Kingdom by Danielle L. Jensen
The strongest version in modern romantasy, because the marriage isn't just inconvenient — it's a cover for assassination. Lara was raised from childhood to marry this king and destroy his kingdom from inside. Every soft moment is a tactical failure on her part, which means the romance and the plot are fighting each other constantly rather than politely taking turns.
2. Serpent & Dove by Shelby Mahurin
A witch married to a witch-hunter, both concealing what they are, both bound by a ceremony neither consented to. The tension isn't will-they — it's how long she can keep the secret that will make him legally obligated to kill her. Forced marriage as a slow-motion detonation.
3. A Deal with the Elf King by Elise Kova
The gentlest entry here and a good gateway. Luella is claimed as the Elf King's bride under an old bargain she had no part in making, and the book is far more interested in mutual thawing than in conflict. Low spice, high yearning, genuinely comforting.
4. Winter's Orbit by Everina Maxwell
A political marriage between two men who are strangers, arranged to hold an interplanetary treaty together — and complicated by the fact that the previous holder of that role died suspiciously. Quiet, careful, and unusually good on the awkwardness of two polite people trying not to intrude on each other.
5. Twisted Games by Ana Huang
Not fantasy, but the closest contemporary cousin to this list: a princess bound by duty to a dynastic engagement, and the bodyguard she absolutely should not want. Included because the structure is identical — obligation on one side, impossibility on the other.
What Makes a Weak One
The failure is always the same: the contract stops mattering too early. If they admit their feelings in chapter twelve and the marriage becomes a formality, the trope has been abandoned and you're just reading a regular romance with a fancy backstory.
The good ones keep the arrangement load-bearing right to the end — the treaty still matters, the crown still matters, and choosing each other has an actual cost.
Where to Go From Here
If it's the enforced closeness you're after rather than the contract specifically, forced proximity romantasy covers the wider trope, and the one bed trope covers its tightest form.
For books where the obligation is destiny rather than politics, try fated mates romantasy.
