Fans of Miss Peregrine's Home for Peculiar Children will not be disappointed in this second book, Hollow City. 
 Actual rating if I'm being a stickler = 3.5 / 5 stars 
 Picking up immediately where the first book left this group, they are leaving the island and are in for quite the sequence of events. My favorite element of this book definitely being the menagerie, probably because I've always had a an interest in them and I'd have to say I don't think I've ever been to one. Back to Hollow City though... 
 The characters seen stronger and more fleshed out then they were previously, and there is a darker tone here. Millard is of course my favorite. But each of them seemed to be more alive to me in Hollow City than they were in Miss Peregrine's Home for Peculiar Children. I couldn't help but wonder if children would stool be children if they'd lived for as many years as they have. I'm off the opinion that the mind and personality would have aged and matured no matter if they were trapped in young bodies. 
 The antique photos were woven into the story quite well. It makes me curious if Riggs had a stack of photos always near by waiting for moments that would erase them in well our of he plotted them out purposefully creating scenarios so that he could insert them. I listened to the first book instead of reading it so I hadn't experienced that part of it before. It was a nice accent to the story. 
 Hollow City was a very enjoyable book but sadly I was not satisfied with the ending. I personally never fancy being left in the lurch. But I know some readers really like that. I do however think that fans of the first book will really appreciate Hollow City. Everything is deeper, darker and so much more well thought out.
