Pretty Little Secret Keeper

Prologue

Alison Lauren DiLaurentis stepped out of the barn. It was early morning, and none of the other girls were awake yet. Which was just how she wanted it.

Alison walked through the dew-soaked grass toward the woods. The early morning sunshine seemed to make her gorgeous blonde hair and her perfect skin glow. Everything around her seemed to be in awe, as everything, including the flowers and the trees, was perfectly still, watching her.

As Alison walked on to meet her older boyfriend, she heard a twig snap behind her. She smiled to herself, as if she knew this was going to happen. Without turning around, she called out, "Oh Courtney, you can come out now!" She heard a rustle in the brush, and then someone came out of the bushes. Someone who had a heart-shaped face; striking blue eyes; long, flowing, blonde hair; and perfect, flawless skin. Someone who was completely identical to her in every way. Alison's twin sister.

"Do NOT call me Courtney. I am Alison, and you know it!" Courtney - or was it Alison? – said.

"Yeah right. Wanna go see if Mom and Dad believe you? Be my guest," Alison #1 replied smugly.

"They wont't. I've already tried to convince them and they don't believe me."

"And whose fault is that?"

"YOURS. It was your fault that I'm stuck in your pathetic little life! You were the one who switched places with me before the charity drive! You were the one who dropped my best friends for those complete losers! You were the one who always pretended to be me, going around the house claiming that you were Ali! It was all because of you. You ruined my life!"

"So what? I HATED those mental hospitals. I had the opportunity to get rid of that life, so I took it."

"So you're admitting that you're Courtney?" the real Alison said suspiciously.

"Sure. But look around Ali. No one is around. No one will believe you," the real Courtney replied victoriously. Alison stared at her sister, her eyes narrowed. She took a step closer.

"You listen to me, Courtney," Alison spat the name out. "I will get my life back sooner or later. And you better believe that this won't end well for you. You. Will be. Destroyed." With that, she turned on her heal and walked back toward her house, but not before she saw a nervous look pass over her sister's face. She smiled to herself.

Let the games begin.
