Rewind to junior year in Rosewood, Pennsylvania, to a winter break no one has ever heard about. . .

Fat snowflakes fall onto manicured lawns, quilted stockings hang over marble fireplaces, and everyone is at peace, especially Hanna, Emily, Aria, and Spencer. Now that Alison's murderer is in jail and A is dead, they can finally relax. Little do they know there's a new A in town. . . .

Rule number one of being an effective stalker: Get to know your prey. So I watch these liars day and night, keeping an eye on the trouble they get into, the messes they make, and the secrets they keep. Hanna's desperate for a very personal session with her gym trainer. Emily is number one on Santa's naughty list. Aria's old flame from Iceland is about to land her in hot water. And Spencer's resorting to some backhanded tactics to get what she wants.

What happens on holiday break stays on holiday break-right? But guess what. I saw. And now I'm telling.

Taking place between Unbelievable and Wicked, Pretty Little Secrets is a very special Pretty Little Liars tale revealing the liars' never-before-seen misadventures over their junior-year winter break.
