Cory is Lauren’s stepmother. She is Mexican-American, and runs the neighborhood school. Of all her children, Keith is Cory’s favorite, which Lauren finds surprising. Cory and Lauren get along well, but after Keith begins leaving the neighborhood their relationship becomes somewhat strained. Cory is kind, but more anxious and perhaps less intelligent than Lauren and her father. She likes the idea of moving to Olivar, even though Lauren’s father warns her about the danger of giving up one’s freedom to live in a corporate-owned city. Cory is killed along with her three youngest sons during the destruction of the neighborhood.
