So here is the list:
Possess By Gretchen McNeil
I heard so many good things about this book. It's really scary I'm told. So those of you brave enough give it a try.
Anna Dressed In Blood By Kendare Blake
I saw the trailer for this and was creeped out. Definitely a read.
Beatiful Creatures By Kami Garcia & Margaret Stohl
I've read this one and it is beautifully written and also scary. Spells, ghosts and graves. Definite fright.
The Underworld... need I say more.
Dracula By Bram Stoker
The mother of all scary books and vampire legends in my opinion. A must read. The first time that I read this it was always during the day and never at night, seriously.
