"Katsa has been able to kill a man with her bare hands since she was eight—she’s a Graceling, one of the rare people in her land born with an extreme skill. As niece of the king, she should be able to live a life of privilege, but Graced as she is with killing, she is forced to work as the king’s thug.
She never expects to fall in love with beautiful Prince Po.
She never expects to learn the truth behind her Grace—or the terrible secret that lies hidden far away . . . a secret that could destroy all seven kingdoms with words alone."From the Publisher's website
