Clary Fray just wants her life to go back to normal - but that turns out to be impossible. For one thing, her mother is still in the hospital, in a mysterious coma. For another, she and her brother, Jace, have fallen under a cloud of suspicion now that the Shadowhunter world knows that Valentine is still alive - and that Jace and Clary are his son and daughter. Not to mention that someone in New York is killing Downworlders and draining their blood, creating a climate of suspicion that sends Downworld Manhattan to the brink of civil war. When the Silent Brothers are murdered and the second of the Mortal Instruments, the Sword of Souls, is stolen, the terrifying Inquisitor is dispatched from Idris to investigate. She clearly harbors a personal grudge against Jace, and she drives a wedge between him and his adoptive family. When Clary's romance with her best friend, Simon, starts to heat up, Jace feels abandoned. But has he, as the Inquisitor accuses, joined up with his father?
