A good book series for a 13 year old?? pleaase read:)?

I highly recommend R.L Stines "The first horror", "The second horror""The third horror", "Trapped". And especially his book "The dead girlfriend". I am very picky and hard to scare.. His teen thrillers are truly gruesome and very well described to the point where you feel like you are in them. They just suck you in.. And have some nice romance plots along with the disturbing core. If you like those, he also has plenty others in his teen thriller stories.
