This is a book cover for Melange Books.
When working on book covers, some of my clients ask for suggestions for their book covers, while others come knowing exactly what they want. For this cover, we went with the latter.

They even had an idea of the stock image they wanted for the skyline (which happened to be from Dreamstime, so that worked perfectly). I put the pieces together and played with color effects to give it the warm, desert glow, then blended everything together.
This is the final result:
