Downloading Masks Worn by Magical Wives

In a world of cold and unsociable mages, Eden alone is the opposite: both powerful and well-loved. Perhaps too well-loved—she's left behind a long string of angry paramours. The exasperated king of the land orders her to settle the issue by taking a spouse.
Despite her friendly facade, Eden would rather marry a stranger than someone who adores her. Nemesia (who has spent decades living devoutly in a hole) is the perfect candidate. Eden welcomes her new bride with warmth and generosity. But one of her oldest enemies ordered Nemesia to accept her offer, and it's only a matter of time till she finds out.
Their marriage of convenience feels strangely comfortable, even with multiple layers of mutual deception. Yet as the seasons turn, Eden begins to lose control over her magic, and Nemesia begins to lose sight of her mission. Secrets unlock deeper secrets as tentative, unwished-for emotions spill over into a relationship that was never supposed to mean anything at all.
