Clare masterfully depicts the world of Shadowhunters four years after the War with Sebastian Morgenstern -- faeries are the enemy, the Law is harsher than ever, and families are still looking for ways to rebuild. This book follows Emma Carstairs and Julian Blackthorn as they work to find who murdered Emma's parents and how to save their city and their makeshift family. The fight scenes are intense, the romance is heart-melting, and the world-building is impressive. Clare never disappoints.
