People may misconceive the reason Bella is holding an apple in this picture. some may think it's because of the Twilight book cover. But it's really about the forbidden fruit theme that's going on in the book. The Myth about Forbidden love is what Twilighters LOVE! the readers love to read about forbidden love between a vampire and a human (kind of like Romeo and Juliet), they aren't supposed to be together but in the end Edward and Bella end up together.
