Shepard, Sara

When one of their tightly-knit group mysteriously disappears, four high school girls find their friendship difficult to maintain when they begin receiving taunting messages from someone who seems to know everything about their past and present secrets.

Forgetting the lessons they should have learned after being stalked by "A," Hanna, Spencer, Emily, and Aria-- high school juniors in Rosewood, Pennsylvania--return to their wicked, deceitful ways, but this time the consequences will be deadly.

Hanna, Aria, Emily, and Spencer have been telling some outrageous stories, but no one seems to believe them, so when a killer comes after them, they wonder if the town of Rosewood will believe them.

Emma is shocked to learn she has a twin sister, Sutton, but on the day the girls are supposed to meet, Sutton is killed, and Emma risks everything to slip into her twin's life and try to bring the killer to justice.
