Everyone knows who Alison DiLaurentis is. Or shall I saw was. She was the Queen Bee of Rosewood. She had the beautiful long, blonde hair. She had the sparkling blue eyes. Every guy wanted to date her, and every girl wanted to be her, that was, until she was murdered.
No one knows who killed her, except the murdered and Spencer Hastings one of Alison's best friends. Alison had four best friends in her clique, Hanna Marin, Aria Montgomery, Spencer Hastings, and Emily Fields. Spencer knows who killed her, but is just blocking it out of her mind, forever. The girls had a different relationship with Alison than most other cliques. They told Alison everything, but Alison told them nothing. Or so they thought.
What the girls didn't realize, was that the whole time Alison was they're friend, she was giving them hints about what would happen to her in the not-so-distant future.
Alison had so much on the girls. She knew all of their secrets, and used it against them to get what Alison wanted. The only thing was, Alison didn't get what she wanted.
A few months after they became friends, around Halloween time, Alison began getting threatening messages from someone who called themself -A. She didn't want to tell the girls, because she thought it was safer for them if they didn't know. But was it really safer?
