Which One Won? What Book Covers Communicate to Readers

The design of a book cover has a huge influence on whether a reader chooses to purchase that book. Therefore, it’s important for authors and publishers to be conscious of a reader’s perception of your cover design.
Take, for example, this PickFu poll of two different book cover designs.
Option A features one person dragging a body through a grove of palm trees, silhouetted against a blue, twilight sky. Option B features a simple silhouette of a cat against a red background. Can you guess which one won?
