Read all about it in my spoiler free review!City of Heavenly Fire the sixth and final book in the Mortal Instruments series by Cassandra Clare.

“On the day Emma Carstair’s parents were killed, the weather was perfect. On the other hand the weather was usually perfect in Los Angeles. Emma’s mother and father dropped her off on a clear winter morning at the institute behind the Pacific Coast Highway, overlooking the blue ocean. The sky was a cloudless expanse that stretched from the cliffs of the Pacific Palisades to the beaches at Point Dume. “

Sebastian is attacking Institutes, causing all Shadowhunters to go to Indris, and Downworlders have been taken hostage. To save them and defeat Sebastian, Clary, Jace, Simon, Alec and Isabelle flee deep into the Demon Realms.


Alright. Let me start off by saying The Mortal Instruments should’ve ended with City of Glass. And City of Heavenly Fire was way too long. Okay, see that? That’s the worst of my negativity flying out the door (or at least a part of it…) City of Heavenly Fire intimidated me badly with its length, I mean, 638 pages? (in my edition, 700+ as a hardcover, OMG!) I think it’s the longest book I’ve ever read. About 25% of it was quite unnecessary to me.

A lot of characters left me cold. Some serious “OMG” stuff went down, but I didn’t really care about it until the very end. The new characters were alright but so unnecessary!  They were fun to read about and they – sometimes – moved the story along, but I didn’t need to read from their perspective. I don’t really know why I didn’t enjoy the characters as much as I used to. My guess is that is was just dragged out for too long.

The plot lost strength because the book was so terribly long. City of Glass was quite short and action packed, which is why I love it so freaking much. City of Heavenly Fire could’ve been so much better if it were shorter! The plot twists weren’t as good as in the previous books and it disappoints me. They were alright, enjoyable and maybe even fun, but I missed the shock factor which makes me love plot twist so much. I didn’t go all “OMG!” at any of them. The Mortal Instruments books grew more serious as the series continued. I used to laugh at these books a lot, but City of Heavenly Fire had some serious lack of humour compared to the rest.

To be honest, all I really cared about were the mentions of anything related to the Infernal Devices. Whether that would be a mention of the London Institute, Will, Tessa or Jem, it didn’t matter. I liked how the events and characters from those books came back and were still such a big part in the story.

The ending was fun, but not that good, honestly. I bawled my eyes out while reading the epilogue in Clockwork Princess because it was fantastic, but the final chapter and epilogue for City of Heavenly Fire wasn’t like that. It did tie up a lot of loose ends and the events were a lot of fun to read about, but it wasn’t all that wonderful.

My Rating

I never rate a book before I review it. But I finished it, it was midnight, Goodreads asked for my rating and I happily hit 5. Thinking about it, it went down to 4. Now, having written this review, I can’t go any higher than 3.

I enjoyed reading City of Heavenly Fire and I’m glad I read all the Mortal Instruments books because I love the series, but it doesn’t deserve a higher rating.
