Eighteen-year-old Sam has always been jealous of his younger brother, Humphrey, the famous "wonder child" pianist. But now that Humphrey is fifteen, the one-time child prodigy isn't able to get any more bookings. Sam’s mother refuses to accept that Humphrey's career is over and devises a scheme to recapture his fame: Sam will compose "new works" by a long dead gypsy composer, and they will tell the world that the composer is dictating the music to Humphrey from the grave. The scheme is a wild success – until some ghostly occurrences convince Sam that the spirit of the dead composer has actually taken over Humphrey's fingers. Have Sam and his family unleashed a force from beyond the grave?
William Warner Sleator III (1945–2011), known as William Sleator, was an American science fiction author who wrote primarily young adult novels but also wrote for younger readers. His books typically deal with adolescents coming across a peculiar phenomenon related to an element of theoretical science, then trying to deal with the situation. The theme of family relationships, especially between siblings, is frequently intertwined with the science fiction plotline.
Due to the suspenseful and often eerie nature of some of his works, Sleator has been compared to young-adult horror writer R. L. Stine. Others cite a strong resemblance to the paranoid, dream-like style of Franz Kafka, which is most notable in House of Stairs, one of Sleator's most powerful novels.
