The Golden Thread

In this third exciting book of the Sorcery Hall series ( The Bronze King ; The Silver Glove ), apprentice wizard Valentine Marsh's newest adventures in magic begin when her musician friend Joel, who is studying violin in Boston, calls on her. For some reason his hands cramp up when he plays, and he needs Val's help to understand why. But she is distracted by other concerns--her grandmother is dying of a stroke. Magical events at a New Year's Eve party seem to lead to the arrival of Bosanka, a sinister girl who says she is a foreign exchange student. She insists that Val and her friends can help her search for her ``people.'' The problem is getting everyone together to create more magic--the unlikely group of conjurers includes skeptics and wise guys. Bosanka's true identity will be a wonderful surprise for readers; her reunion with her people is poetically depicted and touching. Ages 10-up. (Apr.)
