So much fun! And typos have been fixed!
Format: Paperback, Format: Paperback
This was so much fun! Some reviews will mention that the solution is spoiled at the end or there is some misspellings but it should be fixed. In the book you get an option to go to her blog. I 100% recommend checking that and it’s where you will check your answer! I got my whole family into this book and everyone is enjoying finding the name. I definitely recommend if you want to work on something that challenges your brain!

Pages falling out of binding.
Format: Paperback
I love the book. It’s been fun. My issue is the pages are falling out. I received the book today and every other page comes right out of the binding. I am worried I am going to lose pages.

Great mystery concept, poor paper quality
Format: Paperback
Love the concept and the book but the quality of the paper and cover just really disappoints me. Because you have to flip back and forth you’re going to be handling this a lot. I had the book at the pool and the edge got wet and the cover just delaminated and came apart. I have really enjoyed the complexity of this mystery and cannot wait to find out who the killer is!
