Love, blood, betrayal and revenge - the stakes are higher than ever in the fourth book in the bestselling "Mortal Instruments" sequence. The Mortal War is over and sixteen-year-old Clary Fray is back home in New York excited about all the possibilities before her. She's training to become a Shadowhunter and - most importantly of all - she can finally call Jace her boyfriend. But nothing comes without a price. Someone is murdering the Shadowhunters who used to be in Valentine's Circle, provoking tensions between Downworlders and Shadowhunters that could lead to a second, bloody war. And when Jace begins to pull away from her without explaining why, Clary is forced to delve into the heart of a mystery whose solution reveals her worst nightmare: she herself has set in motion a terrible chain of events that could lead to her losing everything she loves. Even Jace. This title is supported by a major marketing and publicity campaign. 'The Mortal instruments series' has over one million books in print.
