Asylum by Madeleine Roux

Age at the back 13+, just thought I would get it out there. I've seen a lot of bad reviews for this, but like I said 13+. People need to remember the age!
Now my thirteen year old self would have had the hairs up on the back of her neck. She would of kept peeking up the dark passage (while reading by touch light, with the bedroom door open)
As it is, my twenty three year old self disagrees. Never mind that though, because over all I can see where she was going with this.
Basically Dan crawford goes to a summer programme at a college/old asylum.
