or here (which includes every teaser posted so far this year, from January on, and one teaser from Clockwork Prince) :
The last CoFA teaser will be in December and will be Clary/Jace. After that, I will not be posting any more teasers, the reason being my publishers will be taking over in the realm of providing promotional content for the book. So there will likely still be "stuff" from City of Fallen Angels being posted counting down to its release — just not by me. I know they have some fun stuff lined up, so I'm looking forward to it.
Cover reveal for City of Fallen Angels is now exactly four weeks away — I've seen it, and it's fabulous. :D
