She knows the rules at the Mount Blessing religious commune are there to make her a better person. Honey hates Mount Blessing and the control Emmanuel, their leader, has over her life.

And when Agness little brother is seriously injured and Emmanuel refuses to send him to a hospital, Nana Pete takes the three children and escapes the commune.
