About This Book
The sharp scent of rain mixes with the electric buzz of the city at night. Clary can’t ignore the shadows that shift just beyond the streetlights—vampires lurking in Brooklyn, werewolves prowling Manhattan. Every secret she uncovers pulls her deeper into a world where danger and magic collide, and nothing will ever be the same.
