In Whitelake village, three witches are forced to sacrifice their magic each year to keep the village hidden and protected from a demon that threatened its destruction two centuries ago.

This year Sky has been chosen. What should be an honour feels like a death sentence to Sky. Refusing to accept her reality, she asks the Fates for guidance and embarks on a journey to reclaim what's been taken.

Her quest leads her to meet others who have had their magic sacrificed, and she learns that without magic flowing in her veins, she will slowly wither away.

When she comes face to face with the demon she's been taught to fear, she realises everything isn't as it seems, and going with him may be the only way to get her magic back.
