Cora is bound to an altar by Gideon and cast into the ocean abyss to be devoured by the mythical Deep King. Instead of slaughter, she discovers tenderness in Soren, the terrifying sea ruler who shares his sacred heart-stone to grant her breath beneath tidal waves.
Their paradise shatters when Gideon ambushes their sanctuary, murdering Soren and shattering the magic stone before Cora's eyes. Awakened in a poisoned enemy stronghold, Cora discovers a miraculous heartbeat kicking within her womb: Soren's impossible heir. Armed with royal oceanic bloodline power and the vengeance of the sea, Cora marches back into the deep trenches not to plead for mercy, but to claim the throne as absolute monarch.
