It is 1702 and Elizabeth Parker, found living on the Massachusetts frontier, is called out as a witch. It is ten years after Salem and nobody, other than Edward Sharpe who calls her out, wants a trial, but the accusation requires a response. It comes as an expedition, to be sent from Boston, to determine if the witch can be scientifically proved.
Isaac Hill agrees to journey ahead of the expedition to prepare for its arrival, though his real mission is to convince Elizabeth to leave the province. Burdened by memories of his past, Isaac is in search of diversion. If he finds it in Felicity Brown, a scarred young widow he meets in Boston on his way to the frontier, and then in Elizabeth at his arrival, he also discovers there is no escaping his own demons.
As the mystery of Elizabeth and her presence on the frontier unfolds, she is put to the test of whether she can overcome her past, Isaac to the test of whether he can find refuge from his past, and the expedition members to the test of whether they have learned the lessons of the province's past.
