City of Heavenly Fire - Cassandra Clare You know what? I nearly forgot about this book until I looked at my messy bookshelf and saw the other two before this one and was like "...wasn't the last one called 'Heavenly Fire'?" and yes I debated about it for several minutes trying to remember this EXACT title.

[prepares self for incoming projectiles]

...but yes, I'll be reading this one, JUST to finish this series off (please no additional books for TIM Clare, just I think you'll rot out my love for your series with it, and even Magnus Bane won't be able to magic your series to salvation for me, just saying).
