Calwyn knows nothing about the world beyond the Wall. She's never seen the golden stone of the city of Kalysons or the wide waters of the Bay of Sardi. She hasn't heard the windworkers' melodies in the Isles of Firthana or the occasional explosions from the colleges of Mithates. She knows only the rounds of her life a a novice ice priestess in Antaris, singing her chantments, and dreaming. Enter Darrow, who speaks to Calwyn of discord in Tremaris, where chanters are hated for their gifts. And Darrow himself is being hunted by a man who was once his best friend and is now the post powerful canter of all. To help Darrow, to escape Antaris, to see the world and perhaps save it, Calwyn will leave the safety of the Wall for a journey with a man she barely knows--and an adventure as beautiful and dangerous as the music of chantment itself.
