The Amazing Marriage Firebox

My Project is a cover for a Kindle Ebook. Title of book is: "The Amazing Marriage Firebox" Subtitle of book is: " And Other Silly Stories Deleted From Your Hard Drive" Author: Francis Ginter The book is a short collection of short stories, all with a information technology theme/background running through them. Most of them are a bit silly or ridiculous, or far fetched. The book cover should convince the reader that the stories are light-hearted and not to be take too seriously. I require source files, (.psd or whatever app you use), one small .jpeg and one large .jpeg.
