So far my 13 (now 14) year old daughter has read all 4 books in this series out loud to me. It's her favorite series of books! She's pretty obsessed with them and the game :). So our reading times have become some of my favorite times for us to spend together. That is probably going to biased my opinions of the books just a little, to be perfectly honest.
That being said, I enjoyed this 4th book in the series the most so far! I think I would have enjoyed it even with just reading it on my own. The mysterious elements were more interesting in this book, and I enjoyed the character development much more.
Highly recommend for middle grade readers who love light horror and mystery stories.
