High Quality Content by WIKIPEDIA articles! Valentine Wiggin is a fictional character in Orson Scott Card's Ender's Game series of novels. She is the older sister of Ender Wiggin.The second child in the Ender family, the International Fleet requested of the Wiggin parents that a girl be conceived because they decided that the boy, Peter, was too brutal and aggressive to be taken to the Battle School. It was thought that by having a girl, the Wiggin family genius could still be used, but in a more humane person. However, the girl was too empathic and too conciliatory for the Battle School program. Because of this, the I.F. requested that a Third (named Andrew, later nicknamed "Ender"), a child who would hopefully balance the two extremes of his siblings, be conceived.
