The Abyss Keeps the Last Surface Breath

Iona Veyr sinks a diving bell into Nacre to steal the last surface breath and save her vanishing island. Abyssal Prince Thalassar catches her inside the fossilized ribs of a Leviathan-city that is being digested from within. His city can survive by forcing Iona’s island beneath the waves. To save both peoples, they must cross pressure markets, stolen sky memories and the truth about Iona’s mother’s design.

A drowning-island cartographer descends to steal the last surface breath, only to face the abyssal prince whose Leviathan-city can survive by sinking her home.
