The year is 1932, and nineteen-year-old Kahlen's life ends and begins in a single night aboard an Atlantic ocean liner. A haunting melody drifts across the waves, bypassing ears to speak directly to the soul. One by one, passengers emerge in a trance-like state. Through eyes clouded with unnatural calm, Kahlen watches her family climb over the ship's railing and plunge into the churning waters below. When she follows them into the frigid ocean, she encounters an ancient consciousness - the Ocean herself - who offers a desperate bargain: join her family in death or serve as a siren for one hundred years. "Anything!" Kahlen gasps, choosing life with desperate instinct. Three inhumanly beautiful women emerge from the depths to welcome her to "the sisterhood of sirens." The transformation is immediate and painful as something ancient floods through her veins. Her mortal imperfections fade, replaced by otherworldly beauty. Most significantly, her voice becomes both gift and curse - capable of producing song so beautiful it compels humans to their deaths. No one warned her about the crushing weight of guilt she would carry for each life taken - every face permanently etched in her memory.
