The Great Magician by Christian Jacq
Thamos, Count of Thebes, is the last keeper of an eternal knowledge, keeping alive the secrets of the pharaohs. Now he has been entrusted with a vital mission. He must leave Egypt for the cold lands of Europe to find and protect the 'Great Magician', a genius whose works will save humanity from chaos. When he encounters a child prodigy, a six-year-old composer lauded throughout Prague, Vienna and Frankfurt, Thamos senses that he's found the one. Is this young musician really the 'Great Magician' foretold by Osiris, the one who can pass on the light of the East to humanity? And if he is, can Thamos succeed in saving the boy from the traps that lie in wait for him?
