The story
Sold into a beast kingdom, she hides as a boy to protect her sister.
When Emeriel and her sister are sold as slaves to Urai, the kingdom of the beasts, Emeriel passes herself off as a male servant to keep her sister safe. But she isn't an ordinary human. She's a Syren, one of the rarest there is, and when the beast king Daemonikai goes feral, nobody but her can calm him. Before long they're secretly in love. Jealous Sinai makes her life miserable, the ambitious lord Zaiper plots against her, and Vladya, who carries a curse, can't stop obsessing over her sister. Through one deadly trap after another, Emeriel fights to keep her secret. And in the end, it's Emeriel who lifts the curse on the beast king, when nobody expected it.
