"Daughter of Earth, you have been chosen to protect this planet. Will you let Gaia's power awaken within you? Will you become... an Angel?"

Quinn thought she knew what she was getting into when she accepted. Growing up reading and watching so many stories of beautiful magical girls, how could she refuse?

But the Angels of Earth don't get pretty sailor uniforms and sparkling transformations. They have four arms and extra eyes, glossy carapaces and glassy wings... and metamorphoses that are excruciatingly painful and anything but glamorous, where human bodies melt into slurry before reforming into their terrifying but beautiful new forms.

And that's to say nothing of the Demons.

Before she realizes it, Quinn finds herself dragged into a world beyond her wildest imagination. A world where ancient orders fight demonic powers for the future of life on Earth. And if she wants any hope of survival, she'll need to find out the truth about Angels and Demons, and all the other mysterious beings that call the Earth their home.
