Cloudbound — Fran Wilde

After the dust settles, the City of living bones begins to die, and more trouble brews beneath the clouds in this stirring companion to Fran Wilde's Updraft.

When Kirit Densira left her home tower for the skies, she gave up many things: her beloved family, her known way of life, her dreams of flying as a trader for her tower, her dreams. Kirit set her City upside down, and fomented a massive rebellion at the Spire, to the good of the towers--but months later, everything has fallen to pieces.

With the Towers in disarray, without a governing body or any defense against the dangers lurking in the clouds, daily life is full of terror and strife. Nat, Kirit's wing-brother, sets out to be a hero in his own way--sitting on the new Council to cast votes protecting Tower-born, and exploring lower tiers to find more materials to repair the struggling City.

But what he finds down-tier is more secrets--and now Nat will have to decide who to trust, and how to trust himself without losing those he holds most dear, before a dangerous myth raises a surprisingly realistic threat to the crippled City, in Cloudbound.
