Steam Submarine the annotated edition


Robert Denethon's most recent book.


Steam Submarine is about Zelf, a Welfing. She travels through universes in a Steam Submarine. Steampunk influenced by weird fiction, this is an epic novel with footnotes that tell the story of the (fictional) author's love for his 'girl with her head surrounded by stars', a love that mirrors the love of Zev & Zelf.


This book is actually four books in one volume: Zelf, Cryptoloup, Into Ultima Thule & First Den.

Cryptogryph the Da Vinci Machine


Set in London, 1851, at the time of the Great Exhibition, two children, Jonathan & Amelia, have lost their parents in a mysterious house fire. They must go on a long journey to find the machine that can answer all their mysteries.

Henry Lawson Hero of the Robot Revolution


This series of two novellas about Henry Lawson, the Australian poet, is set in an alternate universe where the swagman in Waltzing Matilda never committed suicide and Australia ended up as the first Communist Republic in the world. Robots are built to serve the people, but there is a dark secret behind their existence that Henry Lawson works to uncover.

Dragon Den - Chronicles of Marwe book I




Marwe hid in the shadows of a huge pillar-shaped stalagmite that stood beside her like a gnarled, watchful sentry..

She didn’t look up.

What if the dragon looked back at her?

She moved her head and could see her reflection in the pool from a certain angle. A ragged looking, tall-for-her-age ten-or-eleven-or-twelve year old brown skinned girl with large eyes, wearing a warm coat over pants and a shirt that were little more than rags, and no shoes looked back at her. She wiggled her toe and watched the ripples spread. The ground beneath her feet was hard, uneven stone, but she had never owned shoes, so her calloused soles hardly even noticed it - not like rich folk with their soft, sensitive feet - but she was just wasting time thinking about this stuff.

She peered into the cavern tentatively.

Was the dragon home?

No way of knowing. She couldn’t see any further than ten or fifteen feet.


The Day of Dithingstump




In the alternate universe, Adolf Hister has conquered Great Britain and the town of Dithingstump on the West coast is a military base where a small group of rebels is producing a circular and trying to find ways to challenge the oppressors.
