Glass Dagger Press

Mark O'Neill

British spy thriller author and publisher

Welcome to the website of Mark O'Neill, and my publishing imprints - Glass Dagger Press and Samizdat Press.

Under my real name of Mark O'Neill, I've written 32 political and espionage thriller novels, and over 20 other novels in different genres under three other aliases. My main series are Department 89, Edelweiss, and Jack Maddox. The Ghost Sector series was finished last year.

Over the years I’ve published multiple spy thriller series in English, German, French, Spanish, and Italian, building an international readership of people who like fast, intelligent stories without the usual clichés and filler. The books regularly exceed over one million Kindle Unlimited pagereads per month.

Outside fiction, I also blog on a variety of topics. But I never torture people with fake guru nonsense, or “manifest abundance” garbage. I only talk about tried-and-tested practical systems, hard lessons, and strategies that actually work in the real world. This includes a self-publishing guide which details how I automated the publishing business to earn up to $6,000 a month.

This site is home to my books, articles, experiments, and ongoing projects. Have a look around, and search for pages. Look down to your left to find links to all the books. And if you need to contact me about anything, just jump over to the contact page.

The Last Defector

For forty years, Max Keller has been one of Germany’s most notorious Cold War defectors. Now, terminally ill and carrying evidence powerful men thought was buried forever, he returns from exile with one final mission: expose the truth about why he betrayed his country.

Glass Dagger Press - a Publisher Allergic to Political Correctness

Futuristic publishing analytics dashboard

Glass Dagger Press is an independent publishing imprint for thrillers, espionage fiction, political fiction, and romance.

Samizdat Press deals with the edgier stuff - underground publishing, politically controversial topics, online privacy, cybersecurity, and erotica (which pushes the boundaries to the absolute limit).

Basically, the company exists to test the boundaries of political correctness in publishing, and see how much we can get away with in this permanently-offended world. If we manage to meet our monthly quota of offended Karens, then that counts as a bonus as far as we're concerned.

Mostly exclusive to Amazon, the company was built on a simple idea: tell good stories and publish them fast. Traditional publishing moves at the speed of a dead snail and treats authors like disposable office equipment. Glass Dagger Press was created to do the opposite.

Fast writing and faster releases. More creative control over the work. Making and maintaining a direct connection with the readers. No focus-group garbage, sensitivity consultants, waiting a year or more for permission to put a book out into the world, or begging to get the rights back to your own work.

At the end of the day, Glass Dagger Press exists for readers who want sharp stories, honest writing, and books with a bit of teeth. We're not aiming to win the Booker Prize or any other wanky awards. We're just here to entertain you. Judging from the thousands of positive reviews, we think we can say that we do a damn good job of that.
