M'lady's name is Shadowless, cos she's the fastest ship in the sky. And she ain't no everyday airship, she's an aethership, meaning she don't need engines nor turbines nor nowt but an aethermancer and the stars t' guide her.

When luckless Dil falls half-dead onto the deck of the skyship Shadowless, he joins an outlaw crew haunted by visions of maelstrom. Driven by a ruthless captain, guided by a pilot with madness in her eyes, they hunt the power that holds up the clouds. Until it turns - to hunt them.
