Our Vicious Oaths by N. E. Davenport

Fae magic, enemies-to-lovers rivalry, and political intrigue combine in this steamy romantasy from award-winning author N.E. Davenport.

Bound by fate and duty, Princess Kadeesha has no choice but to become the Hyperion High King’s bride instead of the great warrior she knows she can be. But first, she spends one last night of freedom in the arms of an intoxicating stranger.
Unfortunately, Malachi is no stranger. Kadeesha’s husband-to-be decimated the Apollyon Court, and, as its new king, Malachi wants his pound of flesh. When his assassination attempt at her wedding fails, he kidnaps Kadeesha amid the chaos.
But she’s done being a pawn for powerful men. Kadeesha makes a deal with Malachi: she’ll play the part of his lover to lure the jealous Hyperion King to his death and, in return, Malachi will spare her people from the carnage he has planned for his enemies.

To save her court, Kadeesha must navigate a deadly world of fae politics and her growing feelings for Malachi. Though her hatred for him burns bright, it pales in comparison to the fiery attraction each touch between them ignites.
