All citizens within the soaring black walls of Revinia have metal Singers grafted into their skulls at birth. The parasitic machines issue a form of auditory hypnosis called The Music, which keeps their minds malleable and emotions flat. All artistic expression—especially real music—is strictly prohibited. On the edge of the city, nineteen year old Ronja struggles to support her cousins and disabled mother. A chance meeting leads to her kidnapping by an underground resistance striving to preserve the human spirit. Violently severed from her Singer by the brash young agent Roark, Ronja revels in her newfound freedom until the consequences of her disappearance begin to unfold.

After the traumatic events at the dreaded prison Red Bay, Ronja is hanging by a thread. Whispers trail her through the Belly, carrying rumors of her borderline supernatural voice. Plagued by nightmares and haunted by the memories of those she could not save, she clings to the promise that her gift will soon become the weapon of the Anthem. When doubt and arrogance cloud the eyes of their once trusted commander, Ronja and her friends are forced to take matters into their own hands. Armed with little more than an idea, they strike out on their own to silence The Music and The Conductor once and for all. But time is running out, and a new threat is stirring within the walls of the city...

Graceling meets The Bone Season in the long-awaited final installment of the Vinyl Trilogy. Two weeks have passed since the revolution fell. Two weeks since Ronja and Roark fled to the island nation of Tovaire before Maxwell could use her voice as a weapon. Their friends are imprisoned, their comrades radio silent. All the while the new Conductor prepares his unwitting army for a conquest that will ravage the world. With little left but her rage and her voice, Ronja craves vengeance on the puppeteer that enslaved her city and murdered her friend. Her only hope of returning to Revinia lies in the Kev Fairla, the rogue Tovairin army currently engaged in a battle with northern aggressors. The impossible task weighs heavy on her shoulders, and an unexpected blood connection begins to unravel everything she thought she knew. The final installment in the bestselling Vinyl Trilogy, Siren is a story of revenge, rebirth, love, and the limitless power of music.
