Oh gosh, where do I even begin? It was just... mind-blowing. Amazing. Insane. Fantastic. Wonderful. I LOVED IT SOOOOOOO MUCH!!! 
 I absolutely adored this series from the very first page of the first book, and the entire series was just as awesome. I love the eerie, creepiness of it, the characters, the intricate, brilliant, and terrifying plot, and of course, the romance! The conclusion of the series was filled with all of these wonderful things, and oh, how I just loved it. 
 Plus all the Harry Potter references were an added bonus that just made me smile. 
 Throughout the entire series, Jamie has been one of my very favourite characters. He's absolutely hilarious and I just love his relationship with Mara so much. He's so sweet! Can I just have a Jamie please? Thanks. 
 And then there's Noah... Oh my gosh, he's just wonderful. I love him, I love him, I love him, I LOVE HIM! *sigh* He's so sweet, and funny, and hot, and loving, and caring, and absolutely, positively PERFECT. (For Mara and for me) I just wish we got to see a bit more of him in this book. I really, really missed him. 
 And of course, we have Mara. I loved seeing her change throughout the trilogy, even if the change wasn't necessarily... good? I liked how she's such an unreliable narrator, and you don't know if what she's telling you is actually true. It made the story even more complex, confusing (in a good way), and scary. 
 Now, I didn't really love Stella, she was just alright. It really upset me when (view spoiler)[ she left after the whole subway station fiasco. Come on! I mean, yeah, it wasn't Mara's best moment, but that was no reason to just pack up and leave after all Mara and Jamie had done for her. And I was so, so, so, scared and sad when Jamie was leaving. I began crying and had to actually close the book and put it down for a couple minutes. Thank goodness he ended up staying. I honestly have no idea what Mara (OR ME) would've done without him. But I started crying all over again when he said to Mara, "I'm not mad at you. I'm scared of you." What the heck Jamie!?! You were going to kill them too. You just have a bit more control than Mara does, which is completely understandable, considering her "ability'. But whatever. You redeemed yourself later, so I forgive you. And I still love you lots. (hide spoiler)] 
 And I've always liked Jude's character a lot and it was great being able to learn more about him. I really wish that he played a larger role in this installment of the trilogy though. 
 I also enjoyed the development of Dr. Kells throughput this book, but I still don't like her. I don't care what reasoning she had behind actions, she is terrible, terrible person. 
 Okay, so I did rate this 5 stars, but it wasn't necessarily perfect. The conclusion just wasn't entirely satisfying, which was rather disappointing. It was just too open-ended. I have so many questions that were left unanswered. (view spoiler)[ What happened to Jude? What was with the little capsules inside of Mara? What ever happened to Stella? What about the Professor? (hide spoiler)] Hopefully all of these questions will be answered in the Shaw Chronicles, which I am so, so, so excited for! 
 I did love the very last few lines of the book. It finally made al of the pieces fall into place and the beginning of the first book made sense. I actually screamed when I read it, I was just so excited. That was just so brilliantly spun together. I love when those kinds of things happen. It's just so smart and makes me very, very happy for some reason I don't know, but I love it. 
 And just as a side note, this was probably my least favourite book in the trilogy, though I still very much enjoyed it. I just liked the first two a little bit better because I found them scarier, and I got more Noah action. Did I mention that I love him? 'Cause I really, really do. 
 So, in conclusion, READ THIS TRILOGY!!!!!!! It's absolutely fantastic! That's all I wanted to say.
