Mermaid Zephyra dreams of freedom. On the run from a dangerous captor, she's shed her tail and hidden herself on land, her only option to steal and barter on the dirty streets.
But her freedom is short-lived when she's caught and sentenced to death by the beautiful yet brutal warlock Arion Stone. Arion is the strongest warlock alive, but his strength has come at a cost. His only salvation is the God of Death's heart, lost to a fabled kingdom beneath the ocean's depths that only the merrow can reach.
Arion offers Zephyra a deal: help him find the mystical heart, and he'll spare her life. But Zephyra's past is catching up, and as the two enter a dangerous magical bargain, they must learn to trust each other or find that there are worse things awaiting them than death . .
