The Helena Flinn Chronicles

Where dreams are made, nightmares are born.

Beneath the streets of Vienna, a hidden world runs on Nocturnal Energy, goblin ingenuity, and the dreams of sleeping children. One girl holds the key between both worlds.

A middle-grade fantasy trilogy by Michael Sokolar

The Storyworld

The nocturnal world is not a parallel dimension.
It is a hidden layer of our own.

Nocturnal creatures live in shadows and dark places, hidden from ordinary humans. Most people move through the world entirely unaware. A small number of humans know. Very few are permitted to.

Dreams are not random. They are engineered and delivered by goblin field units every night, crafted from templates and filled with each dreamer's own memories and emotions. Children dream more vividly than adults, and the best goblin engineers compete to work with them.

Helena Flinn is twelve years old, chronically sleep-deprived, and one of only a handful of humans who can sense and direct Nocturnal Energy. Among those few, she is something else entirely. Which makes her, depending on who you ask, either the most remarkable person in two worlds or the biggest problem in both.

Setting

Contemporary Vienna, with the goblin city of Vinaborg beneath it

Genre

Middle-grade fantasy, steampunk-inflected

Magic System

Nocturnal Energy — measurable, engineerable, natural

Goblin Language

Raspy, crackling — somewhere between ancient Greek and modern Arabic

Three Books. One Unbroken World.

Book One

Helena Flinn and the Secrets of the Night

The Helena Flinn Chronicles

Helena has suffered from sleepless nights and terrible nightmares as long as she can remember. When she joins a new sleep therapy group in Vienna, she doesn't expect much. Then a desperate goblin arrives at her window with a plea for help — and leads her into a hidden steampunk city beneath the streets she grew up on. Something ancient is breaking through the dream system. Helena, it turns out, is the only one who can stop it.

Book Two

Helena Flinn and the Flickering Realms

The Helena Flinn Chronicles

Almost a year has passed. Helena now moves between two worlds: by day, an ordinary twelve-year-old in Vienna; by night, a regular in the goblin dream factory below. But dream essences are losing their power, nocturnal creatures are mutating, and a shadowy enemy is at work. Helena begins to master intention — the ability to deliberately steer her Nocturnal Energy. She will need it. The ending changes everything.

The Helena Flinn Chronicles

The trilogy reaches its conclusion. Helena Flinn, the Nightmare Squad, and the goblin world face their greatest test yet. The questions left unanswered in The Flickering Realms will find their answers here — and the balance between the dreaming and waking worlds will be settled once and for all.

Almost everything.

The world below Vienna is older than the city above it. These are its inhabitants, its places, its tools, and its rules. Some entries are from the field notes of Kornelius Flinn. Others come from the Shilwani Field Guide of Curious Contraptions. A few are simply things Helena wishes someone had told her earlier.

Six Known Types of Dream

As classified by the Vinaborg Dreamcraft Manual, 4th Edition. One further entry remains restricted.

Normal Dream

Engineered and delivered; the dreamer's subconscious fills the variables. The baseline. Millions produced every night.

Intense Dream

Specially crafted for highly receptive individuals. Requires a senior engineer. Not assigned lightly.

Normal Nightmare

The brain injects difficult variables to process unresolved issues. Not caused by goblins. Usually helpful, in the long run.

Recurring Nightmare

An unresolved issue, on repeat. Treatable via the Mastery Dream technique: invent an alternative ending and rehearse it before sleep.

Daydream

Possibly an unfinished engineered dream spilling into waking hours. Helena is a vivid daydreamer. Whether this is a cause or a symptom remains under investigation.

Lucid Dream

Consciously controlled by the dreamer. Rare. Trainable, to a degree. A building block for something far more significant.

???

The Vinaborg Dreamcraft Manual lists a seventh type. The entry is sealed. Access restricted to senior bureau members only.

Questions. Press. School visits.

Stay in the loop

The nocturnal world has more going on than any one book can contain. Field updates, behind-the-scenes dispatches from Vinaborg, news about Book 3, and the occasional encrypted communication from the bureau's public relay. No noise — only things worth knowing.

The Author

My name is Michael, though most people call me miso. I live just outside Vienna with my wife and two daughters. In my day job, I am the CEO and Creative Director of Little Lights Studio — a Vienna-based film and brand agency with eleven years of experience. I have a long history of telling stories for other people. The Helena Flinn Chronicles is where I tell one for myself.

It began as a short story about goblin dream engineers manufacturing dreams in a lab. The goblins came first. Then the city beneath Vienna. Then Helena. The world grew around them over years of writing.

Both books are available now. The third is in development for 2026. The story is not finished.
