“Tension. Desperation. Guilt. Second chances.What Christopher Ruz has done with Century of Sand is genuinely brilliant.”

– Tom F, Amazon Reviewer
“It’s like if Michael Bay directed Pride and Prejudice. Agent 806 is a bulletproof Kevlar bodice ripper!”

– Fred, Amazon Reviewer
“In The Eighteen Revenges of Doctor Milan, Ruz utilizes his signature dark, excellent quality writing to deliver a sharp science fiction adventure.”

– Will Weisser, Metanautics

Christopher 'Ruz' Hayes-Kossmann

I’m Christopher Ruz, Australian author. I tell lies for money.

I’m a full-time author/publisher working under two pseudonyms. Christopher Ruz is where I publish my serious science fiction and fantasy work, such as my ongoing epic fantasy trilogy Century of Sand and my recent science fiction novella The Eighteen Revenges of Doctor Milan. Meanwhile, I publish pulp spy novellas under the name D. D. Marks, including my most popular omnibus, Agent 806.

  2. Olesia Anderson #8: Wetwork hits Kindle!

    / Leave a comment
    After TEN BILLION YEARS, the next episode in the Olesia Anderson thriller saga has launched on Amazon. Wetwork sees Olesia and her team of miscreants gunning for revenge after their narrow escape from Venezuela. They’re headed to D.C., in search of an old spook who can point them to Olesia’s nemesis, Patrick ‘Rat’ Burroughs. But D.C. isn’t the place Olesia remembers. It’s a warren of spies and senators, mercenaries and murderers, and Burroughs has them all in his pocket. He...

    Another month passes. Still no new releases. What’s going on at Ruz HQ? A lot of writing, actually. This ugly-as-sin diagram shows where I’m at with my three primary projects. Olesia Anderson #8 is currently a 37k word manuscript, will probably hit 40k, and is already 2/3rds revised. It’ll be with test readers soon. Century of Sand 3 is further away from finished – it’s currently a 140k MS, projected to hit 160k (how did it get so big?) and...
  4. Why horror?

    The question a lot of horror authors get is, “Why do you have to write such terrible things?” And my answer is usually, “Um, ah, well, it’s entertaining?” But that’s not really why. I’ve been thinking about what drives me to write horror, and what inspired my series Rust. I could cite a lot of books and shows that I’ve loved (Uzumaki, Twin Peaks, The Ruins) but my love of horror goes all the way back to childhood. And where’d...
  5. New release! WEARY hits Kindle for 99c!

    / Leave a comment
    After a fantastic debut in Apollo’s Daughters (edited by the esteemed Bryan Young), my cyberpunk novella WEARY is available now on Kindle for 99c. That’s less than a KitKat Chunky, the undisputed king of chocolate bars. Weary is a military scifi with cyberpunk undertones that follows a returned soldier, Diana Yossole, working in the ruins of post-war Melbourne. Her deployment in China has left her mostly machine, a well-tuned military engine better suited to destruction than peacekeeping. So when she’s...
  6. Rust Three hits ebook stores, while Rust One joins a Storybundle!

    Such big news! So many cool things! Where to start? Rust. Always with Rust. After months of editing and rewrites, Rust Three is now available pretty much everywhere! Amazon will be the main hub for most readers, but you can also find it on iBooks, Kobo and Barnes&Noble Nook. As for paperback copies… that may take a little longer, but it’ll happen! As to why this book took so long… One: it’s the biggest Rust release so far. Two: I...
  7. State of the Ruz: Rust 3, God Factory, and an interview with Inklings Press

    / Leave a comment
    Ready for Christmas? Still frantically shopping? Waiting for it all to go away so you can go watch Star Wars for the fifth time? Yeah, I get it. I won’t keep you long. Here’s where things are at: Rust 3 is almost done. Aaaaaaaalmost. I’ve gotten some great feedback from first and second round test readers which I’m incorporating into the book now, after which comes a couple rounds of proofreading, and then BAM, done. Will it land by Christmas?...
  8. Rebranding Rust

    For the upcoming release of Rust 3, I’ve gone back to the beginning with a complete rebrand of the Rust series. That means new covers, and the death of the episodic serial structure. Why? 1) The original covers just didn’t work. I have huge respect for the artist, Helen Pinkney: she drew exactly what I wanted, and I absolutely loved her work. But when I took Rust to cons, people would always pick up the books and say, “Woah, great...
  9. We’re Running Out Of Bootstraps (flash fiction)

    “Madam Director? We have a problem.” “When?” “Beethoven. A research squad was sent to observe his composition processes, but he wasn’t there.” “What period?” “1802 onward. He’s simply-” “Calm down, Ms Hart. I’ve seen this before. Who do we have on staff who can play piano?” “Well, there’s old Norris Friar. Works in time-stream stabilisation. He’s quite good, actually. I heard him play at the office Christmas party. And he knows a bit of German.” “Does he have field experience?”...
