She was supposed to birth life. Instead, she became death.

Born of two forbidden bloodlines, Elva was never meant to exist. Half Siren and half Selkie, she failed the one task her kind demanded—bear a child before her twenty-fourth birthday. Now banished and branded useless, she carries a secret even darker than her shame. Her cycle doesn’t just bring longing. It unleashes a monster.

Feared by villages and hunted by those who know what she is, Elva travels the wilds of Torian with her twin brother and his husband, searching for a place that will take them in. But no one wants a Siren who can control men and tear through minds when her needs go unmet.

When the prince's brother offers her everything she's ever wanted in exchange for a single task, Elva must choose: trust a man immune to her song, or give in to the beast inside her.

A romantasy where the siren saves the boy, puts the nobles in their place, and still has time to keep her brother in check.
