A book with medium complexity is the cover that uses one or more images in the background and top of the cover. These images are blended with the book title and the other text resulting in a perfect, eye-catchy book cover that sells more. 

The back cover in these types of books often have an author summary with the author image and spine with the logo as well. 

These are just a few samples of book covers with medium complexity. These are the book covers that are designed using one or more images with a perfect blend of the text and images for a professional appeal. While these covers look simple, designing such covers need expertise in Adobe PhotoShop, Adobe Illustrator, and Adobe InDesign.

Given below are just a few examples of the book covers with medium complexity.
