The Lost Sister — Megan Kelley Hall

BEWARE THE SISTER BETRAYED

Months after leaving Hawthorne, Massachusetts, Maddie Crane is feeling almost normal again. Almost. She still dreams about the Sisters of Misery, the sinister group of powerful girls that ruled her old school, and of a terrible night on Misery Island that led to Cordelia LeClaire's disappearance.

But now an unexpected phone call is forcing Maddie to leave her Maine boarding school and return to Hawthorne to face the wrath of the sister she wronged. In this town layered in mystery, a centuries-old legacy is making itself known again, and Maddie may get all the answers she seeks...at a price.
