The Aural Wyrm. The Thirteenth Chime, #2

The chimes are no longer a secret, and Marrowell is no longer quiet. As the Bellspire's anomalies grow more frequent, Rowan Calder finds herself caught between the protective wisdom of Delphia Crinn and the clinical coldness of Agent Callix Verne. Callix represents a shadowy organization obsessed with mapping improbable events, and he views the Aural Wyrm-the source of the tower's power-as a threat to be contained.
As the town's spirit begins to fray and Mayor Elias Vance struggles to maintain order, Rowan must venture into the tower's original blueprints. She discovers that the Wyrm isn't just a mechanism; it's a living thread of potential that connects every soul in Marrowell-and Callix's "mapping" might just be the thing that severs it.
