Myrcella Baratheon from A Feast for Crows is the daughter of Cersei and Jaime Lannister (although most people believe her to be the daughter of cersei and Robert Baratheon). She is cent to be engaged to the prince of Dorne. Her kingsguard, Arys Oakheart, along with the daughter of Prince Doran sneak her away to meet with some other companions who are plotting to overthrow her brother and put her on the thrown. However, their plot is uncovered and they are attacked. Myrcella is horribly disfigured in the battle.
