Allie is a 24-year-old white woman rescued from a collapsed building by Lauren and her group. Allie and her sister, Jill, ran away from their father, who forced them into prostitution and killed Allie’s baby son. Allie later develops a close bond with Justin, the three-year-old orphan who the group take in after his mother is killed. Allie is suspicious of Earthseed (and indeed of all religion), but eventually comes round to the idea of living with the newly-formed Earthseed community at Acorn.
