Secrets (Pretty Little Liars fan fic!!!!)

Dakota McCoy was the new girl just a little over a year ago, when Alison DiLaurentis, Aria Montgomery, Hanna Marin, Spencer Hastings, and Emily Fields bring her into their clique.
And then Alison disappears. They don't know if she's dead or alive.
All that these girls know is that there is someone out there that knows their secrets and are willing to spill everything...
And endanger their lives.
