This book is a continuation of Clockwork Angel in search of The Magister (view spoiler)[Axel Mortmain (hide spoiler)] and how he came to be so strong in the community. Charlotte is in danger of losing her position at the institute after the great mishap that happened with De Quincy and the vampires. The Clave sends her on a mission of tracking down The Magister if she wants to maintain her position in the Shadowhunters. 
 The Pro(s): Action packed and constantly new issues popping up and happening. Was great at holding my attention the entire time and constantly had me wondering what was going to happen next and grasping my pillow in suspense ha. 
 The Con(s): Jem or Will?! Will or Jem?! You can't have both. Tessa's struggle is really annoying because she only wants Jem as a second choice to Will more so. Jem is such a great guy and deserves much better than he's being dealt. 
 (view spoiler)[ 
 Jem, Will, and Tessa of course play a big role in tracking him down and finding his hiding spot. It is discovered that Axel Mortmain had filed a reparation for his warlock parents that were wrongfully killed leading to his hatred of the Nephilm. Will comes across his sister Cecily that he hasn't seen since she was a child during the search. 
 Through Will talking to Magnus we learn of why he's such an asshole and it's heartbreaking really. To realize he's honestly a good guy but that a demon cursed him that anyone who loved him would die. How sad! He lives a life of forcing people to hate him in order to protect them from himself. 
 & Jessamine! She was fooled by Nate and her desire for love and acceptance. She turned over her own people and their secrets to Nate to help him and The Magister out with their plot. Then when they try to fool Nate again he ends up getting killed by one of his own mechanical creatures in Tessa's arms. So sad! 
 Jem proposed to Tessa - Tessa said yes - Will finally broke down and told Tessa his true feelings - Tessa said no - And now Tessa and Will are both broken. So many tears when Will was finally opening his heart honestly to Tessa only to be turned away.
