This is my first book by Lisa McMann and I have to say I was easily drawn on how she writes. The book was written in a third person point of view, I thoroughly enjoy it but... it was really different. I devoured the book in a few hours but I think the story was quite dragging that it got boring sometimes. 
 I don't really know the concept of a "SCARY BOOK". 
 I think I'm immune or rather I'm not that imaginative enough to feel the creepiness of the whole book. I've tried reading scary books once or twice and it didn't really worked out... well. Ghost, Gore, Zombies or anything written that intendeds to scare me doesn't add up well. 
 The story itself is quite scary, I didn't really get the whole story until the ending. It was a fast paced read but the whole concept didn't really worked out well for me. 
 If you like creepiness and a thrilling story you better read this book!
