A gripping standalone thriller by the New York Times bestselling author of the Rizzoli Isles series In a shadowy antiques shop in Rome, violinist Julia Ansdell happens upon a curious piece of music—the Incendio waltz—and is immediately entranced by its unusual composition. Full of passion, torment, and chilling beauty, and seemingly unknown to the world, the waltz, its mournful minor key, its feverish arpeggios, appear to dance with a strange life of their own. Julia is determined to master the complex work and make its melody heard. Back home in Boston, from the moment Julias bow moves across the strings, drawing the waltzs fiery notes into the air, something strange is stirred—and Julias world comes under threat. The music has a terrifying and inexplicable effect on her young daughter, who seems violently transformed.
