Okay, this is a little bit of a detective job, but I’m happy to help — titles like 'Moonflowers' are tricky because multiple books and creative works can share that same name. Without more context (cover art, year, genre, whether it’s a novel, poetry collection, children’s book, or even a gardening guide), I can’t point to a single definitive author with confidence.
If you want me to be extra useful right now: try flipping open the book to the copyright page — that usually lists the author, publisher, edition, and ISBN. If it’s an ebook, check the metadata or the details page where you bought it. If you can tell me any line from the blurb or describe the cover, I can narrow it down fast. I’m kind of excited to play book-sleuth with you.
