My sister and I listened to this book together a couple years ago and absolutely loved it. I think it may have been the first full cast audio drama we'd ever experienced. Lately, we decided to relisten to it... only to find that we have no motivation to finish. It's a brilliant book the first time around; it's well-written, well-performed, and engaging. But a mystery is never as fun the second time. (Plus, I'm not really in the right mood to enjoy it right now.)
For those who have never listened to The Mystery of Alice, consider this a five star review. This book is basically The Secret History for middle graders—just with an innocent student as the main character, and obviously not nearly as graphic. If you like immersive mystery/thriller, this is for you.
