A Tongue So Sweet and Deadly by Sophia St. Germain

Her words command. Her magic compels. Her freedom? Still just out of reach. In this mesmerizing romantasy debut, A Tongue So Sweet and Deadly launches the Compelling Fates Saga, a four-book series blending court intrigue, forbidden romance, and morally gray characters into a high-stakes tale of power, betrayal, and the fight for autonomy.

From the back cover: 

Half-Fae Eleissa could have had everything. Literally.

Since her magic allows her to compel anyone to do her bidding by merely looking into their eyes, the world was at her feet. But after a tragic accident, she is thrown into the Fae king's dungeons and forced to swear a blood oath to him, binding her to his service.

Five years later, she's living amongst humans in Ellow and has created a life for herself - as best she can, with the king's promise to call in his debt looming over her. When he finally comes to collect, she is made to infiltrate the human elections to determine whether the current regent is involved in the strange things happening in the land of the Fae.

With the promise of freedom from the king's claws, Eleissa is determined to see it through. Liberty is within reach as long as she can keep the lethal Fae guard watching over her from eliminating her before she unearths the information the king seeks.

But as she grows closer to the brooding human regent and secrets begin to unravel, Eleissa realizes greater forces may be at play. 

And she might stand before the choice between her own freedom and that of a nation.
