Well, without more context about this 'Sally novel', it's hard to determine exactly who Sally is. Sally could be the protagonist, a side character, or someone with a special role in the story. For example, in some novels, Sally might be a young girl on a journey of self - discovery, while in others she could be an older woman with a mysterious past.
In these kinds of stories, Sally is usually the main character. She is the one who experiences all the scary events. She could be a curious adventurer who stumbles upon the unknown and has to face her fears. For example, she could be a local in a town full of haunted legends who decides to check out an old, supposedly cursed place. And that's where all the horror begins for her.
Sally could be a fictional character, perhaps a mortal with a unique personality. Maybe she's a kind - hearted girl with a strong sense of justice. Aphrodite, on the other hand, is a well - known goddess in Greek mythology. In this fanfiction, she might be portrayed with all her traditional characteristics like her beauty, her power over love, and her sometimes - fickle nature.
Sally and Percy are likely characters within the context of a particular fanfiction universe. They could be original characters created by the fanfiction writer, or they might be based on existing characters from a book, movie, or TV show.
I'm not sure exactly when the new Sally Rooney novel will be released. Publishers usually announce the release date closer to the time. You could keep an eye on her official website or major book retailers for updates.
