Downloading Clearance To Land: Sapphic Steampunk Scifi and Airships

Where is the line between monster, machine, and man?
Humanity dwells among the clouds in teetering skyscrapers, cut off from the world below. Deep inside the Tower Glorious, in the workshop of Technomancer Elric, a mind awakens. Terravis is a sentient ship designed to go where humanity cannot - down below the clouds to reclaim their lost lands. But Terravis is growing and changing, and how long will she want to obey?
A cozy steampunk/scifi story of emergent AI sentience, tragic sapphic romance, ruthless overlords, and a world choked by toxic smog.
