Jule Welsh can sing. She enthralls people with her bel canto voice. But it takes more than practice to reach her level of exquisite song; it takes siren's blood running through her veins. Jule is starting her senior year at Cougar Creek High when her relatively normal world begins to resemble a roller coaster flying through a carnival scare house. Her mother is diagnosed as insane and committed, a psycho-stalker is snapping pictures of her to put into his homemade Jule-shrine, her voice is suddenly putting people into comatose trances, oh and the gorgeous new guy in town, Luke Whitmore, is interested in her . . . but also wants to kill her.
