(4.5 Stars) 
 *Cue "Rent" music* 
 "Dearly beloved, we gather here to say our goodbyes..." 
 Okay, okay, I'll admit, as much as I want to say, "Well isn't it about damn time this series ended?", I still cried like a baby when I reached the last page of this book. Not only did "Heavenly Fire" more than make up for the god-awful "Fallen Angels" and "Lost Souls," but it also reminded me of why I loved this series so much in the first place. 
 First of all, thank God for Cassandra Clare nixing the whininess of the past two books. Jace, Clary, Alec... everybody was great. The relationships were great, too, and you can tell the author really took the time to emphasize how equal of a relationship Jace and Clary have. It isn't the case that one person is stronger than the other, and because of this they don't feel the need to coddle each other. Like Simon says later in the book, they truly are a team. 
 Simon and Izzy are adorkable as per usual, but in my eyes, Alec and Magnus really steal the show. I don't think I've ever had this many Malec feels throughout the entire series. Their chemistry is great and their back-and-forth relationship dilemma constantly pulled at my heartstrings. Alec was a complete BAMF and sass-master, and it's about time because God knows I would've lost my cool a long time ago if I had to constantly deal with a group of moody 16 year-olds. One of my favorite parts: 
 "You're pining," said Jace. 
 Alec shrugged. "Look who's talking. 'Oh I love her. Oh, she's my sister. Oh why, why, why--" 
 This was also the first time I truly respected Sebastian as a super villain. I feel like this book really fleshed him out as a character, and I was truly terrified of him. You really begin to see the cracks in his "perfectly evil" image, and it makes the story that much more three-dimensional. 
 The plot itself is pretty great: lots of action, a good amount of romance, and a LOT of feels. In hindsight, the book could've been so much more tragic than it was, but boy did I get emotional anyway. As a HUGE lover of the Infernal Devices series, this book was automatically amazing because of all the TID references sprinkled throughout. 
 The only reason I couldn't give "Heavenly Fire" the full five stars was because I thought its length was a little too long. This book is 725 pages, and even though I enjoyed it, I couldn't help but find moments where I kept thinking, "Couldn't this have been cut down??" Clare is wonderful at transitioning between different character perspectives, but often times she would cut from really intense scenes to these relatively calm (and arguably unimportant) discussions between Maia and the other werewolves, and I'd just be thinking, "Really? Can we please go back to the real action at hand?" Also, although I love the L.A. Blackthorn/Carstairs kids and understand that their background is important to the future Dark Artifices series, it kind of irked me that they took up such a large portion of the book. Every time we switched back to their perspective, I felt like the author was putting the story at hand on hold to start building the foundation for a whole other series. I won't get into too much detail about my feelings regarding these overlapping tactics, but I'll just say I'm not a fan. 
 In closing, Cassandra Clare did wonderful justice to this series by writing a fantastic ending that brought me to tears. 
 Ave atque vale: Hail and farewell, Mortal Instruments series.
