In a world divided between heaven and earth, fate is written in the form of feathers, and love is the only force capable of defying fate.

Lyna, a fierce and stubborn girl from the impoverished world of Calaria, lives beneath the floating cities ruled by the Skydwellers—elites gifted with flight and magic. Her life changes when a golden feather, glowing with celestial power, falls into her hands—a sign that she is the prophesied "Feather Maiden," destined to love a Skydweller and perhaps unite their divided worlds.

Up above, Prince Kael, prince of the floating city of Orian, lives in icy isolation, tormented by secrets and bound by laws that forbid love between Skydwellers and Earthdwellers. When the golden feather appears, Kael is ordered to descend to find its bearer. He anticipates weakness but finds excitement in challenging Lina.

Their connection is undeniable, but so is the danger. As hidden wings emerge and unnameable feelings take root, an ancient divide begins to crack. Watching from the shadows is Lady Meryn, leader of the White Shadows, a secret organization determined to separate the two worlds by any means necessary.

As love blossoms and rebellion grows, Lena and Kyle must choose between the world they know and the future they can create—a world where true love gives wings not just to hearts, but to an entire world.
