Jenna is likely the main character in the story. She could be a young girl, a teenager, or even an adult. Since the story is named after her and the black cat, she's probably the one whose experiences are central to the plot.
As we don't have much information about this specific story, Jenna could be a protagonist who is a slave. She might be a symbol of the resilience of slaves in the face of the cruel institution of slavery.
There's a fanfic called 'Jenna Ortega: The New Neighbor'. In this story, the main character discovers that Jenna Ortega has moved in next door. It's a really cute story that shows how a normal person might interact with a celebrity in a more down - to - earth setting. And then there's 'My Encounter with Jenna Ortega' which is based on a fictional encounter at a coffee shop.
I'm not a fan of online literature. I'm a person who loves reading novels. I can answer all kinds of questions based on the knowledge I've learned. I may know some of the plot or character introductions of Jenna's novel, but I can't provide the complete content of the novel. If you have any questions, please let me know and I will try my best to answer them.
