On the jumbled streets of the Island of Lady's Crave live Hark and his best friend Jelt.

They are scavengers: living off their wits, diving for relics of the gods, desperate for anything they can sell.

Something valuable. Something dangerous. Nothing is quite as it seems, and when the waves try to claim Jelt, Hark will do anything to save him.

Even if it means compromising not just who Jelt is, but what he is . . .
