I'm not that familiar with her, but she must be the central figure in this story. Maybe she was someone who went through an extraordinary event related to judgment.
Well, in a story like 'Ellie's Story: A Dog's Purpose Novel', apart from Ellie, the main characters could be the people she lives with. They would be the ones who take care of her, train her, and form a deep bond with her. There might also be some antagonists, like people or animals that pose a threat to Ellie or her family. This would add conflict to the story and help in exploring Ellie's purpose further.
You could simply hand them to her directly. Make sure to have a friendly smile and say something nice like 'I thought you might enjoy these comics, Ellie!'
