“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.

  1. 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...
  2. 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?”...
  3. God Factory in the bag

    / Leave a comment
    I’ve just polished off the first draft of my latest sci-fi novel, God Factory. The first chapter was previously posted all the way back in March as Project Goma, but it’s come a long way since then, developing from a cyberpunk heist tale into a space-opera style swashbuckling adventure. It’s rough and messy, but I think it’s a lot of fun. With that first draft out of the way, I’m returning to polish off a redraft of Rust 3. I...
  4. State of the Ruz

    3 months since my last update? UNACCEPTABLE. Let’s keep it quick and to the point. 1) Olesia Anderson #7.2: Blackout, Part 2, is available now on Kindle! It’s big, it’s bold, it’s explosive, and it’s a hell of a lot of fun. If you’ve enjoyed my Olesia Anderson series in the past, please check it out. 2) I just (as of ten minutes ago) finished the alpha draft of Rust: Season Three. It’s nowhere near ready for external readers, but...
  5. Olesia Anderson #7.1 hits Amazon, and announcing the ImmerseOrDie Storybundle!

    / Leave a comment
    BIG NEWS! It’s been a huge couple days. Super huge. I won’t waste your time by going on about the ups and downs of the past week. Better to get to the point. Two announcements, both of them awesome. The latest Olesia Anderson novella, BLACKOUT PART 1, has hit Amazon! It’s a the first part of a double-length Olesia adventure that sees my favourite spy headed into the badlands of Mexico on a life-or-death operation. No friends. No backup. On...

    I don’t get choked up over celebrity deaths. I mean, they’re interesting people very far away, I’m just a fan of their work, we never shook hands… But Sir Terry Pratchett passed this morning, and I feel I’ve been shaking hands with him my entire adult life, ever since a good friend gave me a hardcover edition of Hogfather for my eleventh birthday. I didn’t understand half of it, but I knew I’d been introduced to something elemental. A story...
  7. Project Goma – Chapter 1

    / 1 Comment
    This is an experiment, the opening to a novel I’m developing very slowly in the background of my other projects. It’s a little sci-fantasy, a little cyberpunk, a little far-future Indiana Jones. This first chapter is more of a prologue, but I hope it’s a fun little read. Take care, everyone. – – – The heist of a lifetime was already going bad when the slam-pup blew Abel out a ninety story window and into freefall. It was a long...
  8. Century of Sand 2: The Ragged Lord

    / Leave a comment
    They ran halfway across the desert to escape the Magician. It wasn’t far enough. After narrowly escaping the burning ruin of the ant tower, Richard and Ana flee with their ally the Kabbah to the Empire of Reason. There, they hope to find directions to the demon Eluah, who can protect them from the Magician and his army of nomads. But the desert won’t give up its secrets so easily, and there are mysteries buried in the sands that no...
  9. Olesia Anderson, rebranded

    / Leave a comment
    It’s been a long time coming, but the Olesia Anderson series has a new art direction. Thanks to the expert modelling and photography duo of Kayla and Phelan Davion, Olesia has a fresh face and a new attitude. This, of course, means it’s almost time to launch Olesia Anderson #7: Blackout! It’s a huge story, the biggest Olesia romp so far, and like Olesia #4: Double Down, will be divided into two parts. It’s a crazy ride that sees Olesia...
