Here’s the Amazon description for Drawn in Ash:
FORCED TO MARRY THE MAN SWORN TO DESTROY HER KIND
The Dynasty claims to be a veritable paradise, where a multitude of races live in peace and harmony. Everys knows better. The Dynasty has been broken since it was founded, with the human nobility oppressing many of the peoples they’ve brutally conquered, including her own. As an illegal mage, Everys hides in a rundown corner of the capital city, running her family’s electronics repair shop, afraid to risk her life to stand against the injustice. But then she brought to the palace and forced to marry King Narius, the descendant of the tyrant who destroyed her people’s homeland, and she realizes this might be the chance she’s been waiting for to make things right.
Due to sacred law, Narius must marry to legitimize his reign. Forced to marry for political gain, he cannot marry the woman he actually loves, so he must settle for another. Unfortunately, the young woman he chose seems determined to cause him nothing but trouble, jeopardizing his plans to bring the Dynasty into a more prosperous future.
Thrown together by circumstances they can’t control, Everys and Narius must set aside old grudges and painful legacies to forge an uneasy partnership before the Dynasty’s enemies destroy everything they hold dear.
