City of Fallen Angels will publish in hardcover in March 2011, followed by a paperback edition in July 2012.
Love, blood, betrayal and revenge — the stakes are higher than ever in City of Fallen Angels. Simon Lewis is having some trouble adjusting to his new life as a vampire, especially now that he hardly sees his best friend Clary, who is caught up in training to be a Shadowhunter—and spending time with her new boyfriend Jace. Not to mention that Simon doesn't quite know how to handle the pressure of not-quite-dating two girls at once. What's a daylight-loving vampire to do? Simon decides he needs a break and heads out of the city—only to discover that sinister events are following him. Realizing that the war they thought they'd won might not yet be over, Simon has to call on his Shadowhunter friends to save the day — if they can put their own splintering relationships on hold long enough to rise to the challenge.

I also have an announcement from Cassandra's blog:
"And the one everyone's been waiting for . . . A lot of you already have intimations of this announcement, given that it was mentioned in Variety and other news outlets — but I wanted to wait until all the contracts were signed and the ink was dry before I said anything. So: the film rights to The Mortal Instruments have been optioned by Unique Features. This is a film production company set up by former founders and co-presidents of New Line Bob Shaye and Michael Lynne, who oversaw the production of the Lord of the Rings movies — probably my favorite fantasy movies of all time. They're very dedicated to fantasy and they understand it, and I definitely trust them with the story of the Mortal Instruments.
Now, a book series being optioned doesn't mean a film is being made right now or is definitely going to be made at all — it means that the studio or production company in question is developing the books as a film project — right now they've nailed down financing and a screenwriter (I don't know who that is yet) and are working towards the next stages in the development project. It is, however, an important step in the movie-making process, so I feel like it's okay to be excited about it. :) "
This is epic, and A-mazing. Well, I want know know what you think so, get on with it!
