Loving her fated mate could doom her entire species.

Kateri has spent her life pretending to be ordinary—laughing with friends, walking among humans, living in a world that can never know what she is. As a Siren, she and her sisters have been hunted by the Rens—male Sirens cursed by the Madness, a disease that once drove their kind to slaughter their own mates. If the Rens ever discover she exists, her species could be wiped out.
