Nightwalker (The Warlocks of Talverdin, 1)

After his guardian dies, Maurey is reduced from student to unpaid servant at his grammar school and bullied because of his black hair and eyes, which make him look as if he is related to the sorcerers who once inhabited the island. When it is discovered that Maurey is indeed a descendent of one of those sorcerers, or Nightwalkers, he is sentenced to be burned alive. He and his young rescuer flee for the Nightwalkers' hidden kingdom. Any reader who enjoys otherworld fantasy, or just a good adventure story, will not be able to put this book down.
