The human origins of Beatrice Porter and other essential ghosts

Sisters Zora and Sasha Porter are drifting apart. Bearing witness to their father's violence and their mother's worsening illness, an unsettled Zora escapes into her journal, dreaming of being a writer, while Sasha discovers sex and chest binding, spending more time with her new girlfriend than at home. But the sisters, like their parents, must come together to answer to beings greater than themselves and reckon with a family secret buried in the past.
