Review title: Perhaps the best Paula Volsky book ever.
Product review: If you like parallel/alternate worlds and dig the French Revolution in world history, then this is a good start for you! Paula Volsky draws very vivid characters here, and keeps the reader interested whether you're in the elegant royal court or in the dirty back streets of the city. It is more a tale of personal struggle than of strategic consequence, but Paula Volsky weaves them all into a wonderful tale.
