Branded a catastrophic omen by imperial seers because she was born without the avian wings of the nobility, Cassia is abandoned in infancy by her father to elevate an imposter named Celine. Raised in loving obscurity by a humble adoptive guardian, Cassia endures constant discrimination from winged aristocrats who view flightless citizens as subhuman filth.
When an apocalyptic storm threatens the sky citadel, the pampered imposter Celine is exposed as the true agent of destruction. In the hour of doom, Cassia awakens blinding golden celestial wings of divine origin, vanquishing the invaders, abolishing the oppressive caste system, and ascending the throne as the true queen.
