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 & everyone is at peace especially Hanna Emily Aria & Spencer. Now that Alison's murderer is in jail & 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 & night keeping an eye on the trouble they get into the messes they make & 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. & 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. & now I'm telling. Taking place between Unbelievable & 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.
