This book is pretty intense for younger teens and preteens. It is very creepy, scary, makes you want to sleep with the lights on if you can sleep at all. And yet,in the end it doesn't make a whole lot of sense. The plot sort of falls apart at the end, lots of weirdness going on but no concrete reasons why. For me, the book had a genuinely intriguing and spooky beginning and the ending fell flat, left me with way too many questions and was a let down.
