City of Heavenly Fire saved the day. I was almost at the point that I forgot everything about this series. I almost forgot what happened. I grew tired of Clary and Jace's forbidden love then now the not touching part. I grew tired of Jace being taken by a Morgenstern and being saved by Clary and being captive once again at the end. I almost forgot what this book is all about and have started to question why Ms. Clare wrote a 4th book when I could have been the best series ever when it ended on the 3rd book. But this book saved the series. It brought back the reasons why everyone love this series. Once again, The Mortal Instruments made me sleepless and can't focus at anything until I finish the story. And it's quite hard, with the number of pages and my busy life. But I pushed through, because this book is worth it.
As usual, the story is action-packed. Every moment matters. I can't even pause for a break in each chapter, the story is exhausting to read. But in a good way. It's just that so much is happening that I'm afraid that when I paused for even a minute, someone would die without me. (haha!)
I love how this specific book is presented. All hope are lost. Even I doesn't have any idea how Clary's group will go through. But I know they will, after all the hardships from the 5 books, they should have the last laugh. I demand it! There's a lot of story going on, in addition with Emma and Julian part, which I'm wondering will be preparation for the next book..oh no. There are still a lot of unanswered questions actually. New mysteries introduced and twist that created a whole different story. But for now, I'm contented with Clary and friends.
I haven't checked yet if there will be upcoming books after this. But I think the story is enough. Let Clary and Jace and their friends rest now and have their happy ending peacefully.
