My book Jacket uses the dark and mysterious side of the book to give it attraction. The book brings humans and the underworld of the fairies together so I used dark a picture of dark colors of the blue and the main character shadowed to give him the effect that he isn't all good even though the light of the moon, which is a central symbol in the book, illuminating him in the back ground. I also used the characters on the spine to give a future reader the information on what type of characters or theme they would be looking at when they began the book.
