There are some girls who have everything...

She has the right clothes, the right friends, and the right last name, but fifteen-year-old Maddie Crane sometimes feels like an outsider in her clique in the wealthy, seaside town of Hawthorne, Massachusetts. And when her gorgeous, eccentric cousin Cordelia LeClaire moves to town, Maddie is drawn toward her ethereal, magical spirit and teeters even more toward the edge of her friends' tightly-knit circle...

Then there are the jealous ones...

Kate Endicott and the Sisters of Misery--a secret clique of the most popular, powerful girls in school--are less than thrilled by Cordelia's arrival. When Kate's on-again, off-again boyfriend Trevor takes an interest in Cordelia, the Sisters of Misery become determined to make her pay...

Now Maddie must choose between the allure and power of the Sisters of Misery and her loyalty to her beloved cousin. But she'll have to give up on ever fitting in and accept the disturbing truth about the town, her friends, her mysterious cousin, and even herself as she faces the terrifying wrath of the Sisters of Misery...
