About the Author


Diagnosed with Asperger’s Syndrome at a young age, Fallon O’Neill has been writing since his sophomore year of high school. These scribblings and vignettes would eventually become the earliest drafts of his debut novel, Geist: Prelude. Dedicated and passionate, Fallon has worked his novels with the Blue Moon Writer’s Group for over seven years, culminating in winning second place at the Will Albrecht Young Writers Competition of 2012, and publication in the eighth issue of the Blue Moon Art And Literary Review. His favorite pastimes include grabbing a beer (or four) at the local bar, blasting soundtracks into his skull, and watching German movies from the ‘20s to keep the existential dread at bay.

Midway through the dull, grey journey of college, Victor Roland, a high-functioning autistic, is dragged into his own world of sword and steam. Here, the year is 1884, by Imperial reckoning. 

In the shadows of its cathedrals, a series of grisly murders sweep the metropolis of Holy Gothica. Soon after his descent, Victor learns of portals in televisions, where daemons lurk in an abyss shrouded in fog, and emerge when blackouts wrack the city. But when he discovers that his friends from “reality” — Charles Garner, a middle-aged “connoisseur of cannabis,” and, Beatrice Morrison, a biker with a goth streak — are trapped in here, Victor resolves to find them, lest they wind up kidnapped by, “the Dollmaker,” and slaughtered behind the screens. 

Fortunately, Victor awakens to the power of Geist — to summon a living facet of his own psyche, to battle the evil born of everyone’s souls. A power that earns him a chance to find his dear friends, and perhaps even a way home … 

Whimsical, humorous yet terrifying, Geist: Prelude will hold readers long into the night, and pave the road for a series of dark fantasy and gothic dystopia.

Sir Hector Thaddeus was once an agent for Her Holiness’s Inquisition. Driven by fanaticism and piety, he carried out many crusades in the name of the Third Gothic Imperium.

Until, he was excommunicated for a sin expunged from the Imperial records. Stripped of all prestige, Thaddeus is trapped in a city once familiar, now foreign. However, one unsolved case still feeds on his conscience—a series of grisly murders committed by “the Dollmaker.”

Now, his duty lies with Victor Roland, once a prisoner, now his only friend and ally.

A man of Earth, lost in this distant world of blood and diesel.

Victor’s journey continues with Thaddeus by his side. Beyond the steeples and slums of Holy Gothica, the investigation takes them into the wasteland realm of an infamous terrorist cell.

Meanwhile, a shadow of Thaddeus’s past moves in the dark, crying out for vengeance…

This is the second installment of Geist trilogy. As a tale of mystery and murderous rebellion, it will take you alongside Victor and Thaddeus on their grim odyssey to justice.

However, be warned. The conclusion that you draw may not be the full truth.
