Seventeen-year-old violinist Moira Alexander joins with an old friend, Jude Osric, in seeking a killer after the sirens who live near their island are falsely accused of murder.

Moira Alexander has always been fascinated by the deadly sirens who lurk along the shores of her island town. Their haunting songs can lure anyone to a swift and watery grave, but she gets as close to them as she can, playing her violin on the edge of the enchanted sea. When a young boy is found dead on the beach, the islanders assume that he is one of the sirens' victims. Certain that someone has framed the boy's death as a siren attack, Moira convinces lighthouse keeper Jude Osric to help her find the real killer. -- adapted from jacket
