Yellow Dawn Novels

cover for Dog Eat Dog, new fiction for SSF with zombies written by David J Rodger

BUY > paperback : from LULU
BUY > kindle: US ($), UK (£), DE (Euro)
BUY > iBook : from iTunes Store


Dog Eat Dog { novel } The Earth has been devastated by a viral pathogen. Only a handful of cities survive intact. The majority of urban spaces have been abandoned to the Infected. Mikhail Drobná and Carlos Revira. Two survivors, both hungry for money and power, and fuelled by a desire to carve their names onto this new world. One provides services of violence and protection for powerful corporate criminals in the Living City of New York; the other is a renegade intelligence agent forever running from the demons of his past. Strangers, until events bring them face to face in a bloody confrontation. Both men seek to sieze their opportunity at whatever cost. But a cosmic Evil has infiltrated the remote corners of these brutalised lands and it has its own plans for this world. Will these men work as one to defeat it or will their bitter rivalry bring about their destruction? In the end, who will devour who?
David J Rodger delivers a novel of epic vision, character depth and nerve-popping tension.


This is really, really good stuff. I'd go as far to say it's the best Sci Fi horror I've read in ten years. I can't think of anything that beats it in terms of action, the innovative ideas per page quota is off the chain, the characters are deep and real. Drobna is the best anti-hero in the genre. A total bad ass, he makes Mad Max look like Stephen Fry.

Cover for The Black Lake - a ghost story within the Cthulhu Mythos by British Sci-Fi & Dark Fantasy Author David J Rodger

BUY > paperback : from LULU

BUY > kindle: US ($), UK (£), DE (Euro)


The Black Lake { novel } The Earth has been ravaged by an event known as Yellow Dawn. Ten years later, survivors are putting lives back together and probing the frontiers of a new Wilderness; whilst overhead the orbital colonies glide across the sky, removed and unaffected. Five men leave the fortress island of Malta on an expedition to the sub-Arctic waters above Scotland. They intend to undertake scientific observations of an alien meteorological phenomenon that has followed the apocalyptic event. What they find is a cosmic horror that seethes amongst the shadows of a shattered Earth. It is a story of escape and wonder, of madness and terror.
David J Rodger delivers a novel that tears open a rent in the boundary of reality, providing a nerve-jarring glimpse of the Outer Chaos and the horrors that hungrily cluster just beyond the threshold of our fragile, human existence.



I raced through Black Lake and didn't want it to end. The detailed descriptions of the locations and unique weather conditions all add to the dark atmosphere. You feel you're there - experiencing the slowly building suspense, dread and fear along with the main character Quint - as the secret of the Black Lake is finally revealed. A good read and crying out for a sequel.

Cover for The Social Club by David J Rodger - a thriller set within post-apocalyptic London

BUY > paperback from Amazon: US ($), UK (£), DE (Euro)
BUY > paperback : from LULU

BUY > kindle: US ($), UK (£), DE (Euro)


The Social Club { novel } The Earth has suffered a cataclysmic event. London survives, but only just, through the authority of the Group that took control nearly ten years ago. When the naked body of a man washes up on the banks of the Thames, the regime in charge tries to dismiss the death as another suicide. Senior Verifier Jadon Purgo has other ideas and as he digs through layers of deceit a gruesome truth begins to emerge... David J Rodger has crafted a claustrophobic vision of survivalism. The horrors of the world after Yellow Dawn are kept at bay through corruption and the idealism of rewarding success. But the real horror is what lies at the heart of this new London. This is a thriller you will not be able to put down or forget.

Blimey! Just finished David J Rodger's The Social Club. It's a superb mystery that builds and builds until, by the end, you can't turn pages fast enough because your heart is thumping so hard it makes your hands shake...

Fantastic! I’ve just finished reading ‘The Social Club’. Fantastic! I hadn’t read a novel for over 20 years at least and I had to ‘learn’ how to read a novel all over again. But it was worth it! The last forty pages (I won’t give the game away!) were a bitingly tense roller-coaster ride and the ending a real ‘gasp’ moment!

A real gem"...a solid addition to a growing collection of books set in a consistent, well-constructed and interestingly portrayed dark future."
