The Faithful Dark: The Sunday Times bestselling unforgettable and darkly gothic mystery set in a holy city on the brink of destruction (The Brilliant Soul Duology)

In a walled holy city where sin and sanctity are revealed through touch, Csilla is a girl born without a soul—a flaw that makes her worthless to the Church that raised her. When a series of murders threatens the faithful magic protecting the city, Church elders recognize a use for her condition: she can assassinate their prime suspect, a heretic with divine heritage, without incurring sin. The heretic offers Csilla an alternative: help him catch the real killer and clear his name, and he will use his angelic gifts to grant her a soul. Meanwhile, Ilan, a ruthless man seeking to reclaim his position as Church Inquisitor, views the case as his path to redemption. He intends to capture the murderer—or, if necessary, Csilla and the heretic—to regain his title. As murders continue and their investigation challenges the all-powerful Faith, Csilla faces an impossible choice: can she achieve salvation without betraying everything she believes in? The novel combines mystery, fantasy, and questions of morality within a holy city on the brink of destruction.
