For the past few years, scandals have rocked Rosewood, Pennsylvania—and high school girls Aria, Emily, Hanna, and Spencer have always been at the center of the drama. They lost friends, became the targets of a merciless stalker hiding under the pseudonym E, and miraculously escaped death. And that's not all. For Aria, the love of her life is on the verge of collapse. Emily discovers her wild side. Hannah kisses her enemy. And someone from Spencer's past - someone she never thought she'd see again - has come back to haunt her. But none of this compares to what happened last spring break. Guess who else found out their dark secret? Now E is determined to make them pay for their crime, and the only thing scarier than E is the fear that maybe they really deserve what's coming to them.
