Heart of Faery by Lesleigh Maeson

The Soul has arrived to save Faery, but my heart might not survive the fight.

Tomorrow is my wedding day. I’m to become the Barren King’s wife to save Faery, but no one is sure that it will work to fulfill the oaths of the past. With the Shades lurking in the shadows, I’m sure that nothing is as it seems. I can’t say I dreamed of a wedding day as a human girl, but if I did, it wasn’t like this.
My power is fueled by the connection to my partners, but right now, they are either in the dungeon or dead. My only option is the possessed man that will become my husband. If I am Faery’s only hope, we are doomed. However, I know there is a power inside of me.The children of the realm sing songs about the Soul of Faery. I have to find that strength, and if I lose myself in the process, I can save a whole world.
I never thought that my kidnappers would be the only men I could trust. I have to break them out of the dungeon. I risk the wrath and the choking thorn magic of Casimir, the Barren King.
