The Mortal Instruments is about a species???? for lack of a better word of humans, who were created by angels to keep humans- or mundanes as they prefer to call them- safe from demons, and unaware of the "shadow world". These protectors, or warriors, or whatever you want to call them are called Shadowhunters.
Clary Fray is our main protagonist character, and she thinks she's just a regular 15 year old New Yorker. That is, until she sees something that her best friend- Simon Lewis- can't see while they're in a club. The something that she sees is 3 people killing what looks like a person. And GASP, you guessed it, Clary's a Shadowhunter. Okay, I know that was a crappy review technique- I just totally spoiled something for you- but come on, it's pretty obvious. And there are so many plot twists in this book, that you won't mind that I spoiled this one tiny obvious one for you. But the book is about her learning about the Shadow world, and having to find her mother, who disappeared, and she has to adjust to this new life that she wants to claim. That's all I'll tell you guys who haven't read the book, so if you're intrigued, go and pick this up, read it, and come back for the spoilery discussion. Bye bye :)
Are you still there? Well, if you are, you've either read the book, or are very bad at following directions. I'll give you one more chance. If you haven't read it, GO READ IT, and come back.
Okay, now if your still here, you must have read the book. I gave you not one, but two warnings. So, now I'm going to delve into the spoilers.
When I started this book, I made the shittiest mistake, and decided to read the whole plot of the book on Wikipedia. I still enjoyed it, and even though I had an idea of what would happen, I was still like GASP when I read that Jace and Clary were siblings and that Valentine was their father. I really feel bad that Jace actually has an attachment toward Valentine, and has to be ashamed of it, because to him, he was a loving father. I do love Jace though. He's so sarcastic and funny, and sweet. When he wished Clary happy birthday it was so cute. Alec, on the other hand, was really annoying in this book. He's like the most uptight of the 5 of the main characters. And, if he loves Jace, but knows it's never going to happen, he has to let go. And he and Jace can't be together because they're parabatai- which are kind of like blood brothers- I guess that's the best way to explain. Basically, they swear to value each other's life more than their own, and it's unbreakable- like an unbreakable vow- and you can't be romantically linked with your parabatai. Oh, and the shadowhunters are really traditional, and they don't really approve of gay people. I mean, Alec's generation is okay with it, but the older generations aren't. Isabelle was really reserved in this book, and she always is, but especially so in this book. I really didn't like her much in this book, because of what happened with Simon and the faerie drink, and just her overall personality. She's better in the other books though. Hodge though, I trusted him-he was like Dumbledore- and he turned out to be a traitor. I understand where he's coming from, and that desperate people do desperate things, and that he may not actually be a cruel person, but that still doesn't excuse him giving Jace up for his own freedom. At the end of this book, I was just like W T F F. Because there's so many cliffhangers, and so many great characters, and great lines.
I feel like this series is comparable to Harry Potter, because of the way it's layed out. We have more than just the romance, and we have all this adventurous badass stuff that they do. I think that any Harry Potter fan will find this series enjoyable.
