Leaving a life of privilege to strike out on her own, Lauren Durough breaks with convention and her family’s expectations by choosing a state college over Stanford and earning her own income over accepting her ample monthly allowance. She takes a part-time job from 83-year-old librarian Abigail Boyles, who asks Lauren to transcribe the journal entries of her ancestor Mercy Hayworth, a victim of the Salem witch trials.
Almost immediately, Lauren finds herself drawn to this girl who lived and died four centuries ago. As the fervor around the witch accusations increases, Mercy becomes trapped in the worldview of the day, unable to fight the overwhelming influence of snap judgments and superstition, and Lauren realizes that the secrets of Mercy’s story extend beyond the pages of her diary, living on in the mysterious, embittered Abigail.
The strength of her affinity with Mercy forces Lauren to take a startling new look at her own life, including her relationships with Abigail, her college roommate, and a young man named Raul. But on the way to the truth, will Lauren find herself playing the helpless defendant or the misguided judge? Can she break free from her own perceptions and see who she really is?
