Self Publishing Success
Mark O'Neill

Welcome to my website. If you’re looking for everything to do with Mark O’Neill, then you’ve come to the right place.

I’ve been writing for the past forty years in some form or another. However, in 2017, I stumbled upon a writing and publishing course, and decided to start making the book writing my main source of income.

I am proud of all my books and the characters that inhabit them. I hope you come to enjoy them too.

My books are currently only on Amazon, but I intend to bring the paperbacks and hardbacks to other retailers in 2024. The books are also currently being developed as screenplays.

For the past 20 years, I have also been a tech journalist and editor, including being the managing editor of five tech websites, and an advisor to businesses wanting to improve their online presence. For several years, I was also an English teacher. You can read more about me on my About page.
