In Clockwork Angel, Cassandra Clare returns to the world she created in her series, The Mortal Instruments. Clockwork Angel, the first installment in the new Infernal Devices series, is set in London, several hundred years before the events in City of Bones. Tessa, an American, is called to London by her brother, only to find him missing and herself a captive, embroiled in a dark world of demons, warlocks, vampires and Nephilim, those descendants of angels who strive to protect the world from the forces of evil.
The London Clave that shelters Tessa is also home to three orphaned Nephilim, each apparently with secrets of their own. The attraction between Tessa and fiery Will takes center stage. But the quiet, mysterious Jem also falls for her, as Will pushes her away. Which handsome young man will get the girl in the end? Can a Team-Jem versus Team-Will fan split be far off?
