In a small desert town where every family keeps a handwritten book of laws passed down through generations, young Mara inherits her grandmother's Deuteronomy—a ledger of rules, confessions, and unfinished sentences. When she discovers a page violently torn from its binding, her search for the missing words unravels the town's founding myth and her own hidden lineage. As old commandments collide with new loves, Mara must decide which laws deserve to survive her. A luminous meditation on memory, obedience, and inheritance, Deuteronomy asks what we truly owe the dead—and what the living must be free to rewrite.
