A lot of f*cked up stuff happens in the finale, but once Adora's arrested, there's a sense of calm and closure. Detective Willis visits Camille in the hospital and says he's sorry for everything. Camille and Amma move to St. Louis, where Frank Curry and his wife almost serve as adjunct grandparents. Camille and Amma seem to be healing. Yes, I know the final twist pulls back the veil to reveal more horror and unrest, but the novel never establishes a sense of calm in the first place.
In the book, we don't bear witness to any tearful prison visits with Adora, nor are Camille and Amma necessarily copacetic with one another. In fact, Amma is needy, prone to intense jealousy, and borderline psychopathic. She's jealous of all of Camille's other relationships and becomes obsessed with female serial killers after moving away from Wind Gap.
