Couldn't ask for a better sequel to such an amazing trilogy. This book had the same thrills and suspense that it's first book had! 
 "Hollow City" takes place right after MPHFPC leaves off. Miss Peregrine, now injured, is stuck in her bird form and the children leave the island and go on a search to get Miss Peregrine back to her normal self again. Meanwhile, they are being hunted by Wights and Hollows. 
 This was a very fast moving plot. The children visit so many places and different time loops that were all fascinating. I love time travel books so I loved how this book had more of a time travel aspect than the first book did. In that way, I think I came to love this book even more than the first one. 
 The character development was further expanded on in this book. We got to know backstories with some of the children and I loved seeing their characters grow. I also enjoyed a lot of the new characters introduced. Some more than others as some new characters came and went. But every new character had their own quirks as some of them were peculiars as well. 
 I'm planning to start the third book immediately. I'm sad to see this series end. But this sequel left off on a cliffhanger so I definitely need to get to the next book right away!
