City of Lost Souls

When Jace and Clary meet again, Clary is horrified to discover that the demon Lilith’s magic has bound her beloved Jace together with her evil brother Sebastian, and that Jace has become a servant of evil. The Clave is out to destroy Sebastian, but there is no way to harm one boy without destroying the other. As Alec, Magnus, Simon, and Isabelle wheedle and bargain with Seelies, demons, and the merciless Iron Sisters to try to save Jace, Clary plays a dangerous game of her own. The price of losing is not just her own life, but Jace’s soul. She’s willing to do anything for Jace, but can she still trust him? Or is he truly lost?

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).
