World Builder. Story Teller.

Aurelia Tessar

Speculative fiction for curious people.

Immersive worlds. Strange ideas. Capable grown-ups. And the possibility that what we think we know isn’t the whole story.

There is always more to discover.

A strange frequency. An overlooked door. A question no one thought to ask.

Aurelia Tessar writes speculative fiction about the pleasure (and sometimes the consequences) of looking closer.

These are stories shaped by wonder, curiosity, beauty and human connection. Stories about people with lives already in progress who discover that the world is larger, stranger, and more full of possibility than they were led to believe.

You are never finished becoming.

What Harmony Forgot

The First Voices • Book One

For thirty years, Cassia Alarian has devoted herself to mastering the six harmonics that hold civilization together.

Then someone builds a machine that can tune them without her.

What begins as a professional investigation becomes something far more unsettling: a journey through altered cities, hidden records, and a history Cassia's Order would rather leave forgotten.

You are never finished becoming.

Enter The First Voices

Six harmonics are said to shape everything. Buildings. Bodies. Music. Emotion. Civilization itself.

For generations, Tuners have maintained their balance. But the first harmony was never six voices.

The First Voices is a five-book speculative fantasy series about resonance, knowledge, belonging—and what happens when a civilization begins remembering what it chose to forget.

About

Stories begin with noticing.

A weathered doorway. An unexpected pattern. A conversation overheard somewhere unfamiliar. The way sound changes inside a particular room.

I’ve spent much of my life traveling, making, designing and asking how things work.

Eventually, some of those questions became worlds.

For readers who haven't finished wondering.
