The popular maxim suggests you should never judge a book by its cover. However, covers are often why we pick up a book in the first place. Before we flip a paperback over to see what the book is about, or open up a hardcover book to read the author’s bio, we are first captivated by their covers. So here’s a list of books you should judge by their covers, and to make this more fun, we won’t tell you what each book is about. It’s up to you to let each image captivate you and lead you to new worlds, dystopian alleys, compelling science, and maybe even a few glamorous parties.
