You can tell that Joelle was a huge fan of Wes Craven way before her shout out at the end. It shines through this book. The references the way the story flows. It had such an interesting twist to the slasher genre. 
The suspense in this book was no joke. Especially with the oujia board scene, I'm not even scared of them myself but I was practically shaking as I was reading scared of what was to come.
