At first the police assume the body is Emma's. Suddenly everyone knows there are two girls who look like Sutton Mercer-and that one of them is dead. But when it comes to finding my killer, she keeps running into dead ends. She's unearthed dark secrets about my friends, my family, and my tangled past. For months, my long-lost twin, Emma, has been living my life and trying to solve my murder. 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. What happens on holiday break stays on holiday break-right? But guess what. And Spencer’s resorting to some backhanded tactics to get what she wants. Aria’s old flame from Iceland is about to land her in hot water. Emily is number one on Santa’s naughty list. Hanna’s desperate for a very personal session with her gym trainer.

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. Rule number one of being an effective stalker: Get to know your prey. Little do they know there’s a new A in town. Now that Alison’s murderer is in jail and A is dead, they can finally relax. Fat snowflakes fall onto manicured lawns, quilted stockings hang over marble fireplaces, and everyone is at peace, especially Hanna, Emily, Aria, and Spencer. Rewind to junior year in Rosewood, Pennsylvania, to a winter break no one has ever heard about.

So could A be Melissa, Spencer's ultracompetitive sister? Or Maya, who wants Emily all to herself? What about Toby, the mysterious guy who left town right after Alison went missing? One thing's for certain: A's got the dirt to bury them all alive, and with every crumpled note, wicked IM, and vindictive text message A sends, the girls get a little closer to losing it all. At first they thought A was Alison, their friend who vanished three years ago. And someone named 'A' is threatening to do just that.

But the most horrible secret of all is something so scandalous it could destroy their perfect little lives. And Hanna's obsession with looking flawless is literally making her sick. Aria is brokenhearted over her English teacher. In the exclusive town of Rosewood, Pennsylvania, where the sweetest smiles hide the darkest secrets, four pretty little liars-Spencer, Aria, Emily, and Hanna-have been very bad girls.
