It is the nature of comets to dazzle and destroy. These eldritch spirits from beyond the stars will grind kingdoms to dust with joyful ease. Only the power of a daughter of the moon can repel them. There are none left.

Aurora knows she is different. Her father is a plain man, and her mother is a mystery. Her prismatic hair, her divergent mind, her inability to weave common enchantments — it must come from her mother’s side. But her mother is gone and no one will say why or where or anything. It’s enough to make her want to fight someone.

And Aurora fights — people, animals, spirits, it doesn’t matter. She doesn’t want to hurt them, but it’s thrilling. She’ll just have to become a hero — heroes get to fight things, right? And heroes get answers to who their parents were.

When a cursed storm leaves Aurora glowing in the light of the full moon, she awakens new powers she can’t control. Powers unheard of, except in those old stories.

But the word on the lips of churchmen is witchcraft — communion with unnatural spirits that spells doom.

Will she defend humanity? Or is she a threat to it?
