Writing a series can be tricky. Sometimes they overstay their welcome, especially when a whole story arc finishes. I'm beginning to think the Mortal Instruments series by Cassandra Clare should have stopped after City of Glass where everything came together quite nicely.

Description (from the Publisher): The New York Times bestselling Mortal Instruments continues and so do the thrills and danger for Jace, Clary, and Simon. Can the lost be reclaimed? What price is too high to pay for love? Who can be trusted when sin and salvation collide? Love. Blood. Betrayal. Revenge. Darkness threatens to claim the Shadowhunters in the harrowing fifth book of the Mortal Instruments series.

Review: City of Lost Souls, in my opinion, is the weakest book in the Mortal Instrument series thus far. The book feels as if it's a pause button while the author gathers her thoughts for the finale. At 534 pages long, it is not only the longest book in the series but also the dullest, most frustrating to read. Normally, I burn through this series because of the nonstop action and great character development; however, with City of Lost Souls I just wanted the book to end.
  It goes without saying that I had a lot of issues with City of Lost Souls, but I will limit them to the big three that made me want to bang my head against the wall: lack of structure, anticlimactic/overdone subplots, and almost to nothing in the character development arena. I would think that with five books under her belt, Clare would avoid these pitfalls.
  The book immediately picks up right where City of Fallen Angel ends, but then the narrative quickly morphs into an amoeba going into different directions as the point of views move from one character to the next. I kid you not. The point of view changes at least ten times within a single chapter, many times without any logical transitions. I felt lost and no longer felt as if I was reading but rather a pinball machine flinging to one place to another. The second arc of the Mortal Instrument series is suppose to focus on Simon (now I have a sneaky suspicious that was all a ruse), an integral secondary character in the series but again the plot and center stage is hijacked by Clace (Clary and Jace) and their romantic turmoil. Instead of sympathizing with Clary or nodding my head in agreement of Jace not being at a good place, I grew tired of their rocky relationship which is more important than the fact that their entire world outside their bubble is falling apart. Both characters who I normally enjoy or in the case of Jace, tolerate, become extremely self absorbed, boring, and repetitive. Due to Clace's relationship angst, everything and everyone is brushed aside. We get clips of arguments with the werewolf council, snippets of homophobia amongst the Shadowhunter society, a few angels and demons summoned here and there, and of course the sexual tension between the various pairs that go teeter on the "are they a couple?" and "are they breaking up?" scale. Yawn.
    Despite these small threads, what disheartened me the most are the stupid mistakes the characters make. It takes them 50 pages to identify the obstacle and then come up with the wrong tactic to correct it. Really? You defeated the big bad with less resources in the first three books and now you stumble, bumble, and fumble to figure out what's right and wrong when the answer is right in front of you? In addition to this, there was a large focus on Jordan's and Maia's relationship, which puzzles me since they were only mentioned mostly in the City of Fallen Angels for a brief moment. I really don't know how this couple adds anything to the overall story arc. Don't get me wrong, I like Jordan and Maia, but their relationship is not important as the other characters that were present since the first book of this series.
   As I mentioned earlier, there isn't much character development in City of Lost Souls. The characters remain stagnant with the exception of a quick glimmer here and there of life, but by then it was almost too late to care. I can, however, point out to all the details of the clothes the characters were wearing throughout the story as there were passages and passages of those descriptions. I'm not convinced that Sebastian is a complex villain. Sure, he's twisted but menacing? Not really. His plot to ruin the world is pretty obvious, but it still takes our heroes and heroines over 500 pages to piece the puzzle together which I figured out in about 200 pages when I wasn't getting motion sickness from the narrative. Heck, even the grand reveal of the master plan and the detailed battle scene fails to bring on the thrills that we expect from this series. By the end of the book, it's pretty clear how things will end with the sixth (and final?) book in the series.
   Now you're probably wondering what did I like in this book? I liked the small moments between Simon and Isabel when they were given limited page time. I also liked the scene where Magnus tried to knock some sense into Alec. There are some great lines here and there that made me chuckle, but that's about it.
   I know there are going to be readers who will love everything in this series, but I expected a lot more from this well established series. Now I'm worried about City of Heavenly Fire which is slated to be published in March 2014 according to Goodreads. For once I think the long wait might be a good thing.

Rating: 2 stars
