I wrote an entire summary for this review add I read it tbh to add to the spoilers section as usual but then deleted it because SO MUCH happened! Summarizing everything in this book just wouldn't make sense if I were to re read my own spoilers because the book was everywhere ha. 
 I'm really happy we finally get past the (view spoiler)[ brother sister awkward romance (hide spoiler)] and learn more details of everyone's past including Jocelyns (Clarys mom). Valentine our villain and (view spoiler)[Sebastian, Clarys real blood brother (hide spoiler)] work together to try and end the Clave by threatening angels. What they don't know though is that you can never fully control angels. 
 It's really hard to talk about this book without spoiling stuff tbh. It didn't make me want to dive straight into the next and I'm still eh about The Mortal Instrument series books and prefer The Infernal Devices. I think I only want to continue the series for glimpses of Tessa and Jem my OTP.
