City of Heavenly Fire

Darkness has descended on the Shadowhunter world. Chaos and destruction overwhelm the Nephilim as Clary, Jace, Simon, and their friends band together to fight the greatest evil they have ever faced: Clary’s own brother. Sebastian Morgenstern is on the move, systematically turning Shadowhunter against Shadowhunter. Bearing the Infernal Cup, he transforms Shadowhunters into creatures of nightmare, tearing apart families and lovers as the ranks of his Endarkened army swell. Nothing in this world can defeat Sebastian—but if they journey to the realm of demons, they just might have a chance…

Cassandra Clare was born to American parents in Teheran, Iran and spent much of her childhood travelling the world with her family, including one trek through the Himalayas as a toddler where she spent a month living in her father's backpack. She lived in France, England and Switzerland before she was ten years old. Since her family moved around so much she found familiarity in books and went everywhere with a book under her arm. Her favorites included the work of the Brontë sisters, the Chronicles of Narnia, Tolkien, Lloyd Alexander's Prydain Chronicles and Susan Cooper's Dark is Rising series. She spent her high school years in Los Angeles where she used to write stories to amuse her classmates, including an epic novel called The Beautiful Cassandra based on the eponymous Jane Austen short story (and from which she later took her current pen name).
