A good book cover will help sell books. From the full page pencils, you will select an illustration (s) (or part of one) for the front and back cover. With this selection you will give the illustrator all of the text for the cover (title, author on front and spine, and some copy on the back that may describe the story or be a bit about the author along with ISNB and barcode). The illustrator will show you a pencil for approval. Revisions are included in this price. If you reject what the illustrator has done and decide to have someone else do the cover, you will owe no further money to Self Publishing US. For the cover.
