In a world where a Grace, a singular and sometimes monstrous talent, marks its owner with mismatched eyes, Katsa has spent her life as her uncle King Randa's enforcer, feared for a Grace she believes is killing. A mission to free an old man from an unrelated kingdom's dungeon brings her up against a Graced fighter, Prince Po, whose skill rivals her own, and the two are drawn into a conspiracy reaching all the way to King Leck of Monsea, a ruler whose own Grace is deception itself. Opens Kristin Cashore's Graceling Realm series.
