I don't think it's ending anytime soon. The story still seems to have some room to develop and there haven't been any strong indications of an imminent conclusion.
One strategy could be to target relevant reading communities. For example, on social media platforms like Goodreads or Facebook groups dedicated to book lovers. You can post about the giveaway, including details about the novel such as its genre, a brief synopsis, and what makes it unique. Another approach is to collaborate with book bloggers. They can help spread the word to their followers who might be interested in a new novel. Also, offering incentives like signed copies or exclusive author Q&A sessions for the giveaway participants can increase the appeal.
I'm not sure specifically as I haven't read it. It could be about a girl who is involved in giveaways, perhaps in a fictional world. Maybe she uses giveaways as a way to interact with others, or it could be part of a larger story about her life and adventures.
