Is There a True Narrator?

With The Poisonwood Bible's structure that splits chapters into different characters' perspectives, it is difficult to discern if the author is trying to emphasize a "main character" that tells the core story/the least skewed version of the Price Family's experience in the Congo. One of the main aspects I love about this novel is the way the reader can tell the difference in voice for each character when they are narrating a chapter. Their voice reaches beyond the clichés of their character, such as Adah being quiet, and the author goes deeper by giving each character (besides Nathan who does not narrate) their own individual way of writing, such as Adah's use of metaphors language. With each chapter being different in the way it is written, determining if there is a central narrator becomes even more difficult. However, after reading through each character's perspective, I feel that Adah is the true storyteller of The Poisonwood Bible. Other than the her lack of speaking to others making her seem as if she is speaking from a third person omniscient perspective (for a majority of the novel), Adah is the true narrator in the way she takes in all the information around her and writing in her journal. From spying on Axelroot and learning about the plan to murder Lumumba, listening to Axelroot's radio, writing new words she learns down, and listening and taking in information rather than being outspoken like much of the other characters in the novel. Adah has the least interaction with her environment (in the way of verbal communication mainly), making her seem as if she is telling the story in full, unaltered, to the reader. The author uses Adah's characteristic of hemiplegia to the novel's advantage, using Adah as a way to poetically tell the deeper meaning of what is going on in the story. Rather than simply telling the reader that the village is overtaken by ants, the author uses Adah to convey the symbolism in the occurrence, relating it negatively to the Bible. Adah's truthful and unaltered perspective convinces me that she is the true narrator, serving as the author's voice.
