Song of the Sea - The Blood Bound Series, #3

The land of Kæ'vale has not seen a siren in over twenty years since they surfaced to aid mankind. Until Æsa is discovered by siren hunters. Soon, everyone is after her-some for show and some for feasting-and others have intentions far more sinister. Jealousy, betrayal, hatred, and murder entrench Nikolai's family, and he flees a violent past. But before his brothers discover his whereabouts, he must do one final thing-and Æsa is the only one to do it.  Æsa despises man and will never trust them..but Nikolai is not a man.
Tragic, powerful, and darkly beautiful, Song of the Sea is the third book in the Blood Bound series.
