The Wicked Ones

Céline Montclaire slips away to the Paris Shadow Market for the same reason she would go anywhere: to escape a family whose cruelty she cannot endure. There she is found by Valentine Morgenstern, who offers her freedom and the heart of the Shadowhunter she secretly loves, on a single condition. At the Shadow Market nothing comes free, and the bargain a lonely girl strikes will echo into the next generation.
