Such is the dark magic of a siren's song, the power of which half-siren Lirien witnesses for himself as he watches his mother sing his father, the King of Ardeth, into the sea. In a fruitless attempt to reverse his father's fate, Lirien sings the siren song himself, not knowing its true power is seduction. Instead, he ensnares his stepmother, the Queen, with its hypnotic melody.

When Lirien refuses her desperate advances, she turns to forbidden magic to force her love on him. But wishing upon a havoc stone is an invitation to chaos. The queen's own son and daughters, Lirien's beloved siblings, are whisked away and transformed into animals. They flee the kingdom, and Lirien chases after them, his beautiful voice also gone.

Through elven mountains, fae forests, and siren waters, Lirien will stop at nothing to find and save his family. Threats come at him from all sides, but there are allies, too-Kitra, a shapeshifting fae fox who vows vengeance on the Queen for killing her brother, and Brandegil, an elf who can awaken the sacred sword Alibrandr to help break the spell on the children.

Together, they'll bring the stars raining down from the heavens if that's what it takes to save Lirien's family, but there's still the matter of breaking the spell on the Queen. And Lirien's own deadly curse haunts him should he stray too long from the sea.
