Foreword by

Philip Fracassi

A feast of good old-fashioned horror, with conflicted characters,

a gooey monster, and plenty of blood and guts.
Tim Waggoner

Author of The Forever House & Bram Stoker Award Winner


“I enjoyed the well-drawn characters, people with real flaws and fears, and loved the setting around the caves of Vik, Iceland.

If you like traditional horror, stories that are scary, fun and even a bit pulpy, The Blackening is for you!”
Michael Griffin

Author of Armageddon House & Shirley Jackson Award Nominee


“Bottom line, O’Connor is a master of creating fantastic entertainment.

Stories with monsters, yes, but the stories also have heart!”

Award-winning author of Behold the Void

In the spirit of Charlie Brooker’s Black Mirror and The Twilight Zone comes Weeping Season — an unsettling, suspenseful chiller that leaves you gasping for breath...

A group of strangers wake up in a cold isolated forest with no memory of anything before their arrival. Lost, hungry and wandering aimlessly, they are summoned to a campsite by a remote entity who controls their fate through a series of tortuous objectives. Their only hope for survival is either escape from the psychological game reserve, known as Block 18, or face mortality at the hands of its maniacal moderator, who loves nothing more than watch his participants suffer.

“Fast, thrilling, and brutal, Weeping Season leaves you gasping for breath.

O'Connor's prose is sharp and lean, and he has a great eye for the grisly.  Thoroughly recommended.”
Tim Lebbon
New York Times bestselling author of The Silence


“I often wonder what it would be like to go back in time and say, ‘I reviewed/just read the debut title from author Stephen King…or Dean R. Koontz…or Ramsey Campbell…or Peter Straub…or Anne Rice’… The opportunity to be there from ground zero with a work from a writer bound for stardom in their field is a great feather in the cap of a reader or reviewer — the chance to claim you were there from the start. That is exactly how I felt while reading Weeping Season.”

“O'Connor has a knack for writing a narrative that is so smooth and fluid, I forget that I'm reading and not watching.

There were scenes in this book that terrified me to my core.”

Stranded deep in the mountains,

Erin Greene finds herself in a battle for survival against the extreme cold.

Heavily pregnant and alone, the clock is ticking and giving birth isn’t her only fear,

for there is something sinister lurking in the dark hills...

And it is hungry…



“Vivid, unflinching, evocative, and original, O'Connor's work

heralds the arrival of an important voice in horror fiction,

one to which you would do well to listen.”

Kealan Patrick Burke

Bram Stoker Award-winning author of The Turtle Boy, KIN and Sour Candy


“O’Connor has given us a story full of life, love, hope, and fear, which takes us to the darkest chambers of our hearts.

A bold new voice in horror fiction that shines like a diamond in a midnight sky above a dark sea of mediocrity.

He gives me hope for the genre.”
Ben Eads
Author of Cracked Sky and Hollow Heart


“The Mongrel is fast, creepy, tense.

This is a no-brainer five star read that acts as a reminder of the continuous stream of literary talent Ireland has to offer.”
