Simon Lewis has been a human and a vampire, and now he is becoming a Shadowhunter. The events of City of Heavenly Fire left him stripped of his memories, and Simon isn't sure who he is anymore.

But the Academy is a Shadowhunter institution, which means it has some problems.

The Lightwoods, the Shadowhunters who run the New York Institute, are expecting a new addition to their family: the orphaned son of their father’s friend, Jace Wayland. Alec and Isabelle aren’t too sure they want a new brother, and their parents are not assuaging their fears, too occupied with the dark news that Raphael Santiago, second-in-command of the New York vampire clan, has brought from the Shadow Market.

When fifteen-year-old Clary Fray heads out to the Pandemonium Club in New York City, she hardly expects to witness a murder - much less a murder committed by three teenagers covered with strange tattoos and brandishing bizarre weapons. Then the body disappears into thin air. It's hard to call the police when the murderers are invisible to everyone else and when there is nothing - not even a smear of blood - to show that a boy has died. Or was he a boy?

All Magnus Bane wanted was a vacation - a lavish trip across Europe with Alec Lightwood, the shadowhunter who against all odds is finally his boyfriend. But as soon as the pair settles in Paris, an old friend arrives with news about a demon-worshiping cult called the Crimson Hand that is bent on causing chaos around the world. A cult that was apparently founded by Magnus himself. Years ago. As a joke. Now, Magnus and Alec must race across Europe to track down the Crimson Hand and its elusive new leader before the cult can cause any more damage.
