Wow the feels! I'm so happy with the way this series ended!! 
 Okay now for a more structured review: 
 At first, I had a hard time settling into the story, and remembering everything from the previous book - this one starts right were the second book, Hollow City, ended. But once I got into it, it was so hard to put down!! 
 (I'm not going to give away too much about the story, just because a lot of people still have to read the first two books, so I'll make this as spoiler-free as possible. BUT I will have the usual spoiler section, so if you haven't read this yet, I suggest you stay away from that ;) ) 
 One thing I love about this series is Riggs's use of old photography, and how he manages to weave old photos into his books. I mean look at the cover! Wouldn't you want to know the story behind such a picture? There's dozens of them like that in the book. On their own, they're each begging to have a story be told about them. Now, they are all linked together in a beautiful story. 
 This book was a rollercoaster of feels. Technically, this series is "YA Fantasy-Thriller". The first two books weren't especially 'thriller-esque'. However, Library of Souls did have quite a few chilling parts. It made it incredibly gripping and made me curious and scared for the characters. This one was definitely my favorite out of the three books :) 
 ((GUYS I JUST ORDERED A SIGNED COPY OF MAGNUS CHASE I CAN'T WAIT TO GET IT!!! )) 
 Ahem, where was I... 
 Oh yeah! 
 The feels: It went through everything - laughing, fear, sadness, worry, happiness... you name it! The end was both awful and amazing! 
 The climax was FANTASTIC and everything a climax should be! 
 As usual with this series, I loved the diversity of the characters, as well as all of their peculiar powers and abilities! Miss Peregrine is an amazing motherly figure. Jacob has the COOLEST power development! 
 Spoiler time! 
 - The ending when Jacob gets sent to the Asylum was awful and so sad. But then when the group figures out they can live in present day, it made me so happy! :D 
 - THE CLIMAX WAS FREAKING FANTASTIC!!! *-* The whole Library of Souls scene was just amazing and awesome and I loved it. 
 - Those lab experiments were creepy 
 - those kidnapped children were creepy 
 - some of the areas were creepy 
 - much creepy 
 - (sorry I'm kinda hyper right now I finished my exams and just read an awesome book, don't judge!) 
 - At the beginning I thought Sharon was like Poseidon - a sea-fareing man, on a boat, with a son called Percy... 
 - Lord of the Rings references always make my day! 
 End of spoiler time :) 
 Overall, this was an absolutely amazing ending to a great series! Now if you haven't read the books yet, go ahead and do so! :D
