Bound to the Fae King by Megan Van Dyke

Wren Dawson spends her days tending to her ailing grandmother and her nights bartending. Orphaned after her parents tragic death years ago, she’s taken on the mantle of the responsible one, trying to keep her splintering family together. Her dreams of travelling the world aren’t going anywhere, and life is great. Mostly.
When thieves rob her bar at closing time, Wren flees into the nearby forest to avoid becoming a grim headline. But her aimless sprint lands her in a whole different world and in the arms of a stranger—Sigurd, Fae King of Air. She’s the spitting image of his long-lost love, and he’s not about to lose her again.
Bound to Sigurd by his magical spell, Wren pursues the one opportunity she has to return home: enter and win a Faery competition where the winner receives a wish granted by the powerful fae cauldron. But Sigurd challenges her in a way no one ever has and sparks a desire she never saw coming. As enemies close in on the Court of Air from all sides, Wren is torn between two impossible choices: seizing victory and returning home, or standing by the side of the king who sets her heart on fire.
