Abby Kimball has slowly accepted her recently discovered ability to see the dead, but none of the harmless sightings she's experienced could have prepared her for the startling apparition of a centuries-old courtroom scene-where she locks eyes with a wicked and gleeful accuser.

As Abby witnesses more fragments from the events in Salem and struggles with the question of how such a nightmare could have come about, she's suddenly confronted with a pressing personal question: Were one or more of her ancestors among the accused? Unraveling the puzzling clues behind that question just might give Abby and Ned the answer to a very modern mystery of their own.
