**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 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.
