Book: City of Lost Souls by Cassandra Clare 

"I always figured a demon would kill me," he said. "A
rogue downworlder. A battle. But I realized then that I just
might die if I didn't get to kiss you, and soon."

Summary (Contains Spoilers)

 Okay so, its two weeks since Jace goes missing and the clave doesn't make much of an effort in finding him, which causes the gang to go to the Seelie Queen for help. The Queen says that she'll help them find Jace, on condition that they steal two fairy rings from the institute for her. Clary attempts to steal them while the institute is deserted, and during her quest, Sebastian and Jace show up in the library looking for books. She's shocked to see that Jace is okay and quite comfortable with Sebastian and doesn't look hurt like she and everyone else thought, after, she steals the rings and meets the gang to tell them about Jace.  That night Jace and Sebastian go to Luke's house to get Clary to go with them, but Sebastian ends up injuring Luke.  (he's okay though). 

They come to the conclusion that Jace and Sebastian are linked to one another, that's why you can't hurt one without injuring the other and also that they might be in another dimension, that's why they can't be traced.  Clary comes up with a plan, using the rings, and goes to Simon. She tells him that she's going to go to the other dimension with Jace but will still be able to communicate with Simon as long as they're both wearing the rings.

 Sebastian and Jace tell her that they will only tell her of their plans after a week so that they can gain her trust. Clary eventually finds out that Sebastian is trying to get a second mortal cup to make dark Shadowhunter's that'll be made with demon blood.  WE GET REAL JACE BACK FOR LIKE A SECOND!!!! He tells her for Sebastian's plan, to mix Lilith's blood and Sebastian's blood in the cup to make the dark Shadowhunter's that'll fight against the Clave. 

Simon's mother abandons him, and he calls his sister, Rebecca, telling her that he's a vampire and is surprised to find that she accepts him regardless.  SIMON AND IZZY VERY CUTE SCENE!!! Team good decide to summon an angel Raziel, after multiple ideas, to get a sword that'll separate Jace and Sebastian (all the while Simon and Clary have cute lil convos). They summon Raziel who gives them the Sword (Glorious) on condition that Simon gives up the Mark of cain. The sword will burn away all of the bad and leave the good in a person. 

Eventually, Sebastian, Jace and a whole lot of other Shadowhunter's are gathered and Lilith is also there (or she's coming idk), and everything horrible is happening. Sebastian is turning people into Dark Shadowhunter's and Clary is trying to reason with Jace but he's ignoring her and EVERYTHING IS GOING TO HELL when ALEC and everyone else shows up!!! Simon passes the sword to Clary and she stabs Jace in the chest and heavenly fire bursts through his entire body but he doesn't die. Sebastian gets away (obviously).  The heavenly fire went INTO Jace which is now a wholeee other problem but at least we have normal Jace back.

Magnus and Alec break up because Alec went to Camille for answers and also considered stripping Magnus's immortality from him.  We then find out that Camille is DEAD because of small crazy girl Maureen (Simons stalker whose now a vampire).

Rating: 4/5

Thoughts: THIS BOOK WAS SO SO FUN TO READDD!!! SO much was happening all at once and we got to see Izzy and Simons relationship become more than whatever was going on initially, Maia and Jordan are now sort of a thing WHICH I TOTALLY SHIP. I honestly thought that Sebastian wasn't entirely too bad (ngl) during those two weeks but then we obviously got to see that he's actually a WHOLE other kind of evil and manipulative and ugh Hate that guy. Also we got SO MUCH OF BROTHER ZACHARAIAH (JEM CASTIERS if you've read the infernal devices, you'll know who I'm talking about). 

I really enjoyed that Simon was basically the reason that Jace was saved. Cause if it wasn't for him then things would have been sooo much worse.  Also I really enjoyed them waking every few days in a different country/city. That was really cool to read and really enjoyable. I LOVED WHEN JACE BECAME JACE FOR LIKE A FEW HOURS AND HE WENT TO CLARY AND WAS LIKE 'ITS REALLY ME" OMG I CRIED. I also cried when she stabbed him with Glorious and everyone thought he was dead for like a few minutes. I sobbed during that part. Overall really pleased with this book and I'm sad that their story is going to end soon. 

Memorable Scenes/Lines:

"It's like there's always been a piece of my soul missing, and it's inside you, Clary."

" f the chance comes before me to save the last of the Herondale bloodline, I consider that of higher importance than the fealty I render the Clave."

"I knew you were there too, I could feel it."

"He still loves you, said Brother Zachariah, and his voice was surprisingly gentle. You are the central point about which his world spins. That has not changed."

"He'd burn the whole world down till he could dig you out of the ashes."
