One morning, in the spring of 1815, Mary hears her beloved cousin Duncan calling desperately for her help. But Duncan is 3,000 miles away in Upper Canada, and to journey to him means leaving the safety and comfort of home for an unknown wilderness. Answering the call, Mary finds herself battling dark forces in a foreign land. But as she struggles for her survival and independence, she unexpectedly finds friendship – with cheerful Yankee Patty, with Owena, the quiet Indian who recognizes the healing powers in her, and with Luke – so different from “Duncan the black.”
