Acacia, a Book of Wonders by Vincent James

From Texas Review Press:

 Acacia, a Book of Wonders tells the story of Petra Caldwell, the matriarch of Acacia, a new religious movement located in a densely wooded East Texas thicket. In this non-space of surreal and mystical happenings, the saints of Acacia worship birds as prophetic emblems and prepare for a prophesied end-times event known as The Commotions. All the while, Petra wrestles against the wiles set for her by her predecessor, the Prophetess Mother Salome Nightingale. Acacia, a Book of Wonders affords a unique vantage point in cult fiction: a narrative told from the perspective of the group’s leader.
