The survivors of San Madrigal’s sinking escaped to New York and still dream of finding a way back home. But Mateo, now a high school junior and piano prodigy, just wants to get the attention of music legend Gerval. He gets his chance on the night of the Grand Fete, an annual party celebrating the blended culture of pirates, Cuban Santeros, and Sephardic Jews that once created San Madrigal. But the evil that sank the island has caught up with the survivors. After he witnesses a brutal murder, deadly secrets unravel, and Mateo awakens a power within himself that could unlock the mystery behind his lost homeland.
