Nora Coppens is a fictional character, so her age is not specified. It is up to the author or creator of the character to determine her age. In most cases, the age of a fictional character is not tied to a specific year such as 2024. Instead, it is usually based on the timeline and events within the story or narrative in which the character appears.
In the case of Nora Coppens, if she is a character in a book, movie, TV show, or other form of media, her age would be determined by the creator of that work. It is possible that Nora Coppens is a young character, perhaps a teenager or young adult, but without more specific information it is impossible to determine her exact age.
Ultimately, the age of Nora Coppens is a detail that is left up to the imagination of the audience or readers, and may not have a definitive answer.
