I can't believe it's over. I have to wait 1½ years to read a new Shadowhunter book ?!
I loved every second of the 5 months I spent reading this series.

A few thoughts about the books, and the incoming Wicked Powers serie (spoiler for the whole Shadowhunter Chronicles) :

– Tatiana's death felt extremely anticlimactic for someone who's been in 6 books, and the main villain of 3 of them
– Christopher's death for kinda unnecessary ? It feels as though it was here just for shock value. We could've at least actually seen him die, or see his funeral, or even his parents react. It's a lot like Max's death
The Lightwood kinda seems to be cannonfodder in TSC, one of them dies in every series (Benedict in TID, Barbara & Christopher (and Tatiana) in TLH, Max in TMI, and Robert in TDA). They die more than any other family. That actually makes me pretty scared for TWP.
And then close second are the Blackthorns with Rupert in TID, (Tatiana in TLH), Andrew in TMI, and Arthur and Livia in TDA.
The Lightwoods and Blackthorns are the families with the most members in 2014 with 5/6 people each. How likely are they to all make it out ?!?!?
– I hope there won't be any love triangle + forbidden/impossible love in TWP because I feel like we've seen it all with the previous books, and it's starting to be annoying. Please, just let it be Kit and Ty figuring themselves out, and Dru redeemin Ash.
– Will Bridget be important ?! She was hit by heavenly lightning and became immortal. Surely that's gotta mean something.
– Why can Kit fire James' gun ?! What does that mean ?! What will it do ?! Will Belial or Liltih recognize it ?!
– Will the Blackthorn sword be relevant ?!?!
– Livvy can only be seen by her brother and a Herondale, just like Jesse was visible only by his mother, sister, and Lucie. Is she I  the same place he was ?! Will there be a link between their fate ?!?!
– Will Heaven intervene again ?! Will we learn what that other time they did was ?!
– Will the existence of paladins be important ?! Maybe someone could become one ?!
– And the wandering souls of Silent Brothers and Iron Sisters ?!?!
– Why did Belial came back ?! How come Sebastian could seemingly easily kill an angel, but Princes of Hell just come back ?!
– Where is Lucifer ?! Stuck somewhere ?!
– Cortana can "kill" Princes of Hell, will that be useful again ?!
(Also, love how according to the stories characters read, it can or cannot kill Belial, and in the end it killed him bit also did not kill him.)
– Will Jessamine be relevant ?! Surely she has lots of knowledge about Princes of Hell.
