Here's a pretty snow-globe scene for you:

It's December of Hanna, Emily, Aria, and Spencer's junior year. Snow is falling, blanketing Rosewood's manicured lawns and dusting the tops of luxury SUVs. Christmas lights brighten every window, and cherub-cheeked kids are busy making their lists for Santa. The whole town is at peace, especially the pretty little liars.

Now that Alison DiLaurentis's murderer is in jail and A is dead, they can finally relax. But little do they know that I'm going to pick up where A left off. I'm going to be the new A, and I've made a list of my own. Guess who's at the top of the naughty column? That's right: Hanna, Emily, Aria, and Spencer.

And these liars been bad! Hanna got caught shoplifting and totaled her ex-boyfriend's car. Emily defied her parents so many times they sent her away to Iowa. Aria's after-school smooch sessions with her English teacher got him fired. And Spencer may have been the naughtiest of them all. Stealing her sister's fiancé wasn't enough—Spencer also took her economics paper and pushed her down the stairs when Melissa found out what she'd done. Tsk tsk. These liars deserve coal in their stockings—or worse. Luckily I'm here to make sure they get what's coming to them.

It's only a matter of time before the pretty little liars get their hands dirty again—especially now that they think A is gone. So what trouble will they get into next? Well, I'll just have to lie low…and watch. I'll watch and watch and come to understand exactly what kind of bitches I'm dealing with. I'll find out everything.

And once I do, I'll know how to take them down.

Let's start with…Hanna. This girl's undergone some major upheaval. Her mom ditched her for Singapore. Her estranged dad is moving in with his Stepford fiancée and he perfect daughter, Kate. At least Hanna has her loyal boyfriend, Lucas. Or does she?

Let's the stalking begin!
