The Crown of Embers (Girl of Fire and Thorns) by Rae Carson

Description

She does not know what awaits her at the enemy's gate.

Elisa is a hero.

She led her people to victory over a terrifying, sorcerous army. Her place as the country's ruler should be secure. But it isn't.

Her enemies come at her like ghosts in a dream, from foreign realms and even from within her own court. And her destiny as the chosen one has not yet been fulfilled.

To conquer the power she bears, once and for all, Elisa must follow a trail of long-forgotten—and forbidden—clues, from the deep, hidden catacombs of her own city to the treacherous seas. With her go a one-eyed spy, a traitor, and the man whom—despite everything—she is falling in love with.

If she's lucky, she will return from this journey. But there will be a cost.
