One Heartbeat explores and answers the question arising from a child’s innate curiosity about animals and whether they have a heart like humans. The story takes the reader and listener on an adventure to meet a variety of animals, to touch their hearts and realize they too feel pain and pleasure, sadness and joy. Harry discovers that all living beings deserve kindness and love, ‘just like you and me’. One heartbeat gently guides child and parent alike through the critical moral imperative of acknowledging personhood in all animals. By using the vibration of the heart as a signifier of our commonality, Harry embraces the simplicity of a deep morality binding all creatures in a covenant of mutual respect and compassion.
