When Feliu Delargo is born, late-nineteenth-century Spain is a nation slipping from international power and struggling with its own fractured identity, caught between the chaos of post-empire and impending Civil War.

Feliu's troubled childhood and rise to fame lead him into a thorny partnership with an even more famous and eccentric figure, the piano prodigy Justo Al-Cerraz. The two musicians' divergent artistic goals and political inclinations threaten to divide them as Spain plunges into Civil War. But as Civil War turns to World War, shared love for their trio partner -- an Italian violinist named Aviva -- forces them into their final and most dangerous collaboration.
