I read Christopher Pike's Chain Letter when I was seven.

Also, try googling Sydney Sheldon's Master of the Game. Also was about seven or eight when I got my hands on that one. Yikes.

Also, zomg Face on the Milk Carton. I wanted to be the Face on the Milk Carton XD Mostly in that sort of "omg hate you all want a new family" type of angsty way lmao
