I am really glad I listened to the audio on this one. It wasn't explicitly written as a diary, but the narration definitely had that feel. The audiobook narrator really embodied the character in a way that made it feel authentic. I think it would have felt more gratuitous if I had read it in print. Turning an unassuming character into a hero shouldn't have been unexpected, but it was both surprising and super satisfying. I loved that it still managed to be a portrayal of Black Joy, even in the face of hardship and evil.
