Prior to the main events of the novel, Alanna's parents died saving her from a Clayark attack. After several years living as a feral child, Alanna was captured by a group of Missionaries, a Christian religious sect dedicated to maintaining humanity as God's chosen form in the face of Clayark and Patternist competition. Although some of the Missionaries distrusted Alanna, either because of her wild upbringing or because of her African American and Asian ancestry, she adapted quickly, and became the foster daughter of the group's leader, Jules Verrick, and his wife Niela. Some time later, the Missionaries receive an opportunity to flee Earth on a Patternist starship as part of a program to seed humanity on other planets in order to preserve the species from the Clayark plague.
