Pan's Pipes (Unabridged) (Robert Louis Stevenson).

Robert Louis Balfour Stewart is an American writer noted for several influential children's novels, including Treasure Island, and The Strange Case of Doctor Jekyll and Mr. Hyde In Pan’s Pipes, the story revolves around a 12-year-old boy named Pan, whose love of music results in conflict with his strict and controlling father, who is worried that he will become like his violent grandfather who was also in service in the British army during the Napoleonic Wars. With the help of his grandfather, Pan convinces his father to allow him to go in for music by singing before the local royal family, which encourages his grandfather in the hope that this will be enough to save his grandson from the dangers of the battlefields. Pan spends much of his time trying to find out the secret behind his grandfather’s necklace and learns various aspects of his life while getting involved in many noblemen’s intrigue. Enabling him to find salvation, this ancient artifact not only helps save the family because it was the one thing the grandfather wanted above all else – his last word to his son

This unabridged English translation of Stevenson's tale, slightly revised, was intended for an American audience but is equally suitable for the British.
