A gripping standalone thriller by the New York Times bestselling author of the Rizzoli & Isles seriesINTERNATIONAL THRILLER WRITERS AWARD FINALIST • NAMED ONE OF THE BEST BOOKS OF THE YEAR BY LOS ANGELES TIMES AND SUSPENSE MAGAZINE 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 Julia’s bow moves across the strings, drawing the waltz’s fiery notes into the air, something strange is stirred—and Julia’s world comes under threat. The music has a terrifying and inexplicable effect on her young daughter, who seems violently transformed. Convinced that the hypnotic strains of Incendio are weaving a malevolent spell, Julia sets out to discover the man and the meaning behind the score. Her quest beckons Julia to the ancient city of Venice, where she uncovers a dark, decades-old secret involving a dangerously powerful family that will stop at nothing to keep Julia from bringing the truth to light.Praise for Playing with Fire “Compelling . . .
