But when an unmarked envelope arrives at her dorm containing a single ominous tarot card, Maddie realizes with terror that some secrets won't stay buried. Knowing she must return to Hawthorne--a town still scarred by the evil of the Salem witch trials--Maddie prepares to face the fears of her past. . .and the wrath of the sister she wronged"--P.
