It came with the exclusive letter from Jace to Clary :)
City of Fallen Angels is the 4th book in The Mortal Instruments Series. It's proceeded by City of Bones, City of Ashes, and City of Glass. I'm probably hyping this book a bit too much but this series is definitely something you should check out if you haven't already.
Cassandra Clare will be on tour and so will Holly Black. Click here to see the schedules. Lucky for me they will be stopping by Portland,OR on April 13! See you there if your in the Portland area. :)
Here's a little summary of City of Fallen Angels:
City of Fallen Angels takes place two months after the events of City of Glass. In it, a mysterious someone’s killing the Shadowhunters who used to be in Valentine’s Circle and displaying their bodies around New York City in a manner designed to provoke hostility between Downworlders and Shadowhunters, leaving tensions running high in the city and disrupting Clary’s plan to lead as normal a life as she can — training to be a Shadowhunter, and pursuing her relationship with Jace. As Jace and Clary delve into the issue of the murdered Shadowhunters, they discover a mystery that has deeply personal consequences for them — consequences that may strengthen their relationship, or rip it apart forever. Meanwhile, internecine warfare among vampires is tearing the Downworld community apart, and only Simon — the Daylighter who everyone wants on their side — can decide the outcome; too bad he wants nothing to do with Downworld politics. Love, blood, betrayal and revenge: the stakes are higher than ever in City of Fallen Angels.
