DEA eBooks & audiobooks are not limited to the standard eBook cover art and content. Because each digital book is a unique asset, you can have hundreds of unique cover designs that can help drive desirability and collectability. eBooks & audiobooks can now contain bonus content such as audio, video, images, art, special messages to the readers, and many other exclusives. This is a new experience for readers and a great new way for publishers/authors to build lasting relationships.
