Achord: The Last Frequency

By Seren Vael

In the empire of Tessaly, the Harvesting is not theft.
It is infrastructure.

At sixteen, every citizen surrenders their Chord - the invisible frequency humming at the centre of the living soul - to the Weave. The Weave powers the empire's cities, warms its winters, runs its trains through the dark. You go on living after. You simply go on living more quietly.

The people who've had it taken are called Nulls. They look like people. They move like people. If you didn't know what a soul looked like from the inside, you might never notice what's missing.

Seraph Voss is five days from her Harvesting.

Then she touches a dying Null in a street in Sector Pale - and something impossible happens. Every frequency she's ever carried, stacked inside her like an archive of every Chord ever stolen from every person who ever lived, reaches for his dying soul and says: no. Not yet.

His eyes blaze. Four windows crack. A drone drops from the sky.

Seraph runs.

Because what she just discovered is this: she is an Achord - a soul that resonates on every frequency simultaneously, the first in four hundred years. Enough power to run the empire for a millennium. Or enough to return every stolen Chord to every hollow body the empire has ever quietly unmade.

The empire finds out the same night she does.

Now Seraph has three days to learn to be whole - to master a power she didn't know she had, inside a resistance organisation that has been building toward this moment for forty years, guided by a boy whose fractured, regrown soul heard her frequency from across the city and simply, without permission, began moving toward it.

Caelum Rath is the High Conductor's son. He has been performing loyalty to an empire he despises since he was thirteen years old. He is made of broken music. He is the only one who understands what she needs to become.

And his father is already coming.

ACHORD is a breathtaking YA dystopian debut - for readers who loved the soul-deep romance of Shatter Me, the fierce stakes of The Hunger Games, and the lush world-building of A Court of Thorns and Roses.

Perfect for readers who want:
- A heroine who becomes something the empire built four centuries of infrastructure to prevent
- A slow-burn romance between two people who are too much to be emptied
- A resistance forty years in the making
- A world where your soul is infrastructure - and taking it back is revolution
