Wynter has lived on the outside for eight months. While her sister Joy finds life away from the cult increasingly difficult, Wynter is growing stronger. She begins to open up to her brothers about her childhood and gains confidence in dealing with the world, even manipulating her siblings' useless father into stepping up at last.
When a horrific accident threatens to tear everything apart, it seems Wynter's dreams of a happy family may be destroyed. Meanwhile, Joy reveals a secret about someone from Wynter's past, and the family dynamics head in a new direction that no one asked for.
