The Betrothed (The Betrothed #1) by Kiera Cass
A would-be queen. A handsome king. A perfect match . . . or is it?
When King Jameson declares his love for Lady Hollis Brite, Hollis is shocked—and thrilled. After all, she’s grown up at Keresken Castle, vying for the king’s attention alongside other daughters of the nobility. Capturing his heart is a dream come true.
But Hollis soon realizes that falling in love with a king and being crowned queen may not be the happily ever after she thought it would be. And when she meets a commoner with the mysterious power to see right into her heart, she finds that the future she really wants is one that she never thought to imagine.
