Seeing Things

Cameron James is weird.

Her wardrobe is made up of a few dozen miss-matched items of clothing, half of which are either ripped or messily patched up. She refuses to participate in any form of sport. She's shut-in, yet charming, strange yet interesting. She is extremely blunt and her life story can be summed up in fifty words or less:
she was left an orphan when she was six after her parents were murdered during a drug deal gone wrong, she moved to Mexico for about ten years before coming back to America and now she is seeing ghosts, but she doesn't know that.

Now there's a guy named Shawn who won't quit bothering her and her main priorities include unpacking all her moving boxes, settling into this new American high school and keeping up to date with all the homework.

But on top of all the stuff she has to get used to, who is the weird guy who keeps lurking around looking like some sort of stalker?
Is he a friend or an enemy, but most importantly.....is he even real?
