Seren has survived nineteen years in the Hollow by keeping her shadows hidden.

But when they take a life she never meant to lose, she's dragged into the gilded city above - a prisoner of the very institution hunting her kind to extinction.

Kael is a scholar of the shadows, sent to observe and contain. What he finds instead is a girl whose darkness doesn't just answer her - it remembers something older than either of them.

As ancient shrines awaken beneath the city and a goddess stirs in the dark, Seren begins to understand that her shadows were never a curse. They were always a calling.

And the light will do anything to silence it.

She was never meant to survive. She was meant to become something else.
