Any niche can be written to sell. Driven by story and with the target reader in mind, I write books that sell.
I have written books on commission and self-published. On Amazon, direct sales with a traditional publisher. In the Czech, US, and British markets.
With a PhD in history and a successful copywriting career, I sure know how to do the research that your book needs.
