Shadowhunter Emma Carstairs may have finally avenged her murdered parents, but life has only grown more complicated. She's learned that the law prohibiting parabatai Shadowhunter warrior partners from falling in love is not just a precaution but a rule rooted in real, violent magic. Emma and her parabatai Julian have already violated this law, but only Emma knows the truth, and she struggles to find a way to make Julian fall out of love with her. But Julian and his siblings are in danger, and Emma and Julian will have to join forces if they want to prevent all-out war between Shadowhunters and Faeries. Clare leaves the Shadowhunter world to dig into Faerie lore; fans of Holly Black will recognize her influence here. The story strains its 700-plus pages, and at times, the widely diverse cast feels more like a checklist, as not all characters are fully developed. But there's enough blood, gore, and forbidden love to satisfy the most ardent of Clare fans, and with that cliff-hanger ending, how can they not come back for book three?--Reagan, Maggie Copyright 2017 Booklist
