This book is good because you know what that they are going to find something but you don’t know what. It is very exciting and I would recommend this book to someone else.

I thought that this book was absolutely amazing! My favourite character was Jack Carter, because he says some really irrelevant stuff, has the occasional stroke of genius, and is sometimes really stupid. It interested me because i love mysteries! I would recommend it to somebody else, but also they should read a couple of the other books to because this one is late in the series.

I have read this book 2 times because it is very adventurous and I like adventures. The scariest part in the book is when they meet the hooded man with a black eye and a white eye. It was a fiction because it was a story book and non-fictions are books with facts in them. My favourite character was Emily because she always carries a emergency bag with her and she never forgets to bring her note book. I would recommend it to somebody else because I think it is a fun book because as you go along you can try and solve the mystery at the same time as they do.

It is a bit scary at times, but I still think it is really good. It's about some people who like solving mysteries (so do I!) and they discover a secret room and find out the mystery of it...

This book is a mystery book which I enjoyed a lot . It is the typical mystery book in which some people find clues to a amazing place or object but someone else is looking for it too
