After a girl she knows from school goes missing and is found dead in the Red River, Feather is shocked when the police write it off as a suicide. Then, it's Feather's best friend, Mia, who vanishes -- but Mia's mom and abusive stepfather paint Mia as a frequent runaway, so the authorities won't investigate her disappearance either. Everyone knows that Native girls are disappearing and being killed, but no one is connecting the dots. When Feather's brother Kiowa is arrested under suspicion of Mia's abduction, Feather knows she has to clear his name. What Feather doesn't know is that the young serial killer who has taken Mia has become obsessed with Feather, and her investigation is leading her into terrible danger.
