The Citadel has been silent for a decade, its grand stage a graveyard of glass and memory. Until now. When Elara, a lowly apprentice with a voice that shouldn't exist, is thrust into the spotlight of the legendary Solstice Gala, she unwittingly wakes the sleeping heart of the mountain. But she isn't singing alone. From the flooded ruins and shifting shadows beneath the theatre comes a voice—ancient, scarred, and possessive—that promises her the dream she has longed for. As Duke Kaelen of the Royal Guard, fights to keep her in the world of sunlight, Elara is drawn deeper into a symphony of shadows. To save the kingdom from a magical collapse, she must decide: is the voice in the dark her savior, or the architect of her destruction? In the High Citadel, every note has a price, and some echoes never die.
