A's making a list and checking it twice. Rewind to junior year in Rosewood, Pennsylvania, to a winter break no one has ever heard about. . . . Alison's murderer is in jail, A is dead, and the pretty little liars can finally relax. Or so they think. But there's a new A in town—me. I'm watching these girls day and night, and you won't believe what I've uncovered. Hanna's desperate for a very personal session with her 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.
