This is a fun and cute middlegrade book. The supernatural elements are interesting (and sometimes pretty spooky) but the emotional core of the book is very rooted in real-world kid issues: navigating relationships with family and friends, dealing with fear and loss, treating yourself and others with respect. Plus, any book that is anti-home owners associations is alright by me. 
I listened to the audiobook and while there were a few sections that I believe are illustration-only in print that did not in my opinion fully work as sound effects, the narration by Caitlin Kelly was generally very strong and added to the atmosphere nicely.
