(Cassie confirmed that it's Jonathan & Clary Morgenstern on the cover. On the inside cover will be Jace, Alec, Izzy, Simon, and Maia. Unfortunately, they couldn't fit Magnus!)
It's with some trepidation that I wait for this book... I really can't wait to read it but I'm a little scared judging from the snippets Cassie's has revealed so far. @TMI_Source has them all here. People will die... but who!? oh my heart hurts just thinking about it!
City of Heavenly Fire comes out 27th May 2014 in Australia and it is 733 pages long!!
