"Shadowhunter Emma Carstairs and her parabatai Julian Blackthorn patrol the streets of Los Angeles, where vampires party on the Sunset Strip, and faeries - the most powerful of supernatural creatures - teeter on the edge of open war with Shadowhunters. When the bodies of humans and faeries turn up murdered in the same way that Emma's parents were when she was a child, an uneasy alliance is formed. This is Emma's chance for revenge, and Julian's chance to get back to his brother Mark, who is being held prisoner by the faerie Courts. All Emma, Mark, and Julian have to do is solve the murders within two weeks...and before the murderer targets them." -- From the publisher.
