TL;DR: if you want to read any of this series only read this one.
The first time I listened to part of this audiobook I was around 12 and my mom had checked it out from the library. I remembered thinking then this family had some serious mental health issues. When I saw it on my library's digital collection I had a touch of nostalgia and only a vague memory of what it was about so I listened to the whole series. I can now safely say this is the only book worth reading. I this book is the only one of the three with a storyline outside of the flashbacks that allows the story to flow. Over all it's an average book that made me feel nostalgic about listening to audiobooks with my mother while working over a puzzle. Also 12 year old me was right.
