<p> In picture-perfect Rosewood, Pennsylvania, ash-blond highlights gleam in the winter sun and frozen lakes sparkle like Swarovski crystals. But pictures often lie—and so do Rosewood's four prettiest girls. </p> <p> Hanna, Aria, Spencer, and Emily have been lying ever since they became friends with beautiful Alison DiLaurentis. Ali made them do terrible things—things they had to keep secret for <i>years</i>. And even though Ali was killed at the end of seventh grade, their bad-girl ways didn't die with her. </p> <p> Hanna's on a mission to corrupt Rosewood's youth, starting with a very attractive sophomore. Aria's snooping into her boyfriend's past. Spencer's stealing—from her family. And pure little Emily's abstaining from abstinence. </p> <p> The girls should be careful, though. They thought they were safe when Ali's killer was arrested and A's true identity was finally revealed. But now there's a new A in town turning up the heat. And this time Rosewood is going to burn. </p>
