Why do some ebooks sell better than others?

A Science Fiction hit

One of the things that interests me is what makes a book sell?

I have asked myself this question often; several of my science fiction ebook selection sold well for years, while other sci-fi ebooks never sold.

I stopped hoping for sales in the UK; I know the market here is more challenging than the US market to crack unless you have an established name, and how can you get that if no one buys your work?

The ebook above was my hope of starting some UK sales interest in my work as a writer with a fantasy story, but like many more, it fell by the wayside; I did plan a series of this had sold.
