Z9 City: Front cover design for space sci-fi novel

This is what a business in United States was looking for in their book cover design

I need a front cover for a sci-fi space novel: "Z9 City: Champion of Daoqin". It's about two boys who have grown up in a colony of space stations far from Earth. If you look that up on Amazon you can read the description and preview pages, and see the horrible cover I designed just to get the book out (yuck!). A ship named Mirage is described in the preview pages, along with a description of Z9 City (the main space station). Maybe those things can be used for the cover. The dimensions of the cover are 5.5" x 8.5" (plus 1/8" bleed on top , bottom and outside). I will do the spine and back cover and if I select your design I ask that you tell me which fonts you used. I have access to all the Adobe fonts. Read more
