Once a century, one person is chosen for greatness.
Elisa is the chosen one.
But she is also the younger of two princesses, the one who has never done anything remarkable. She can't see how she ever will.
Now, on her sixteenth birthday, she has become the secret wife of a handsome and worldly king—a king whose country is in turmoil. A king who needs the chosen one, not a failure of a princess.
And he's not the only one who seeks her. Savage enemies seething with dark magic are hunting her. A daring, determined revolutionary thinks she could be his people's savior. And he looks at her in a way that no man has ever looked at her before. Soon it is not just her life, but her very heart that is at stake.
Elisa could be everything to those who need her most. If the prophecy is fulfilled. If she finds the power deep within herself. If she doesn't die young.
Most of the chosen do.

The second book in Rae Carson's award-winning The Girl of Fire and Thorns fantasy trilogy, perfect for fans of Game of Thrones and Kristin Cashore. Tamora Pierce called the first book, The Girl of Fire and Thorns, "A unique and engrossing read!" A seventeen-year-old princess turned war queen faces sorcery, adventure, untold power, and romance as she fulfills her epic destiny.
In The Girl of Fire and Thorns, Elisa won the war. She saved her kingdom. But no one prepared her for how hard it is to recover from a battle, or to rule a people who still don't trust her. She's still fighting—against assassination attempts and more—and her enemies lie both outside her court and within it. So Elisa will cross the ocean in search of the perilous, uncharted, and mythical source of the Godstone's power. With her go a one-eyed warrior, a loyal friend, an enemy defector, and the man she is falling in love with.
