Are there specifications for the back cover?

Good question - thank you for asking! There are no design specifications for the rear, but it will have three text sections, including a paragraph at the top that describes the contents of the book, another paragraph that describes each author, and a third paragraph that describes the series. Let me know if you have any additional questions!

Thanks for your invitation but I'm more into web design and development.
I would love to hear about if you're in need of web development/coding.

Looks like great project, I´m currently working on my proposal and will be uploading shortly.
