Pretty Little Liars by Sara Shepard

Hello!
You may not know me. I'm A. My mission? To destroy these Pretty Little Liars once and for all. Sadly, this series is not in my PointOfView otherwise you'll know who I am. And we can't have that, can we?
This series is about 4 girls: Emily, Aria, Hanna, and Spencer. They each have dirty secrets that I know about, so I have total control over them. Let me tell you about their past, which is very important. They were best friends with Alison, who was pretty, popular, and had everyone wrapped around her finger.
Then one day the clique were having a sleepover in Spencer's barn. Spencer and Alison had a fight, Alison stormed out. Nobody ever saw her again.
Many were sad to see her go. But not me. I was thankful.
So now, I send text messages, emails, and letters threatening the 4 girls. It's so fun to watch them cower in fear and do everything I tell them to. Too bad blackmailing is illegal. Oh well, that doesn't stop me!
That's it for now.
TTFN,
A

P.S. This is Alisha's most favorite book in the world, so yes, it did beat Twilight.
