"The Red Necklace: A story of the French Revolution" and its sequel "The Silver Blade" are set primarily in France during the Revolution and the Reign of Terror, also in contemporary London. They feature an aristocratic girl and a gypsy boy who are 12 and 14 years old when the story opens. The boy Yann has been trained to assist a stage magician but has or develops genuine magic powers; a starred review (unusually good) by the American service "Kirkus Reviews" labels even "The Red Necklace" fantasy.
