This book was just okay. It had some interesting twists and turns, but I kind of figured out who did it, just not how we got there. This book was seriously messed up at times, though. There was like Games of Thrones level family drama. 

The scavenger hunt game was fun, but it was more one you watched than got to participate in as the reader. The clues were very specific, and they weren't something the reader could puzzle out.

All in all, I'm glad I listened to it while doing other things. I wouldn't recommend it for the mystery game part, but if you want something really dramatic, give it a go.
