The Moonlit Woods by Eliza Tilton

When marriage or death are your only options, you break all the rules.

Rosalie is sold to the magistrate of Farrow’s Gate to compete in a marriage competition. If she wins, her home is saved. If she loses, she’ll be forced to work off her family’s debt in an undisclosed location.
But the magistrate won’t just marry any human. He wants a mate whose magic rivals his own, and Rosalie can’t ever reveal just how powerful she is. In the world of Saol magic is regulated, and if the Magi Council discovered what she is, it won’t just be her life at risk.
Her only chance of escape is with the magistrate’s bodyguard, Baine: a dark, too handsome fae, and one who has no interest in helping a human girl.
Until one night in the moonlit woods when everything changes, and suddenly Rosalie is torn between what she wants and what is right.
Losing the competition means death, winning means the death of others, and Rosalie is out of time. If she doesn’t choose soon, someone will do it for her.
