Hey, that's an awesome book. It talks about a girl and her best friend, who learn that there is a phantom haunting their school over the years and begin to explore that. R.L. Stine here, promises an amazing twist ending. What I liked the most about this book is that besides being spooky and extremely creepy, it is also interesting with small details. Thank God for its one of the best Goosebumps books yet. And yes, thanks to the Open Library. While reading I truly wished if its story never ends. So, book lovers, I recommend this piece to you! Happy reading.
