Charlotte Harper's best friend Jessica is shocked to receive a letter detailing Charlotte's journey back in time to save her possible ancestor Elizabeth. The letter, written in 1819, speaks of the consequences of Charlotte's actions and asks for Jessica's help. Charlotte's adventure begins with a Wiccan ritual and spell that takes her back to 1818. After arriving at a small town on the shore of Owasco Lake, New York, she settles in, finding work at the general store to earn her keep. While awaiting Elizabeth's arrival, she forms strong bonds with those around her, finding herself part of a tight-knit circle of friends and deeply in love. Charlotte knows that walking through one door often closes many others, so when she dreams of warnings from the future she left behind, she wants to understand. Is Jessica reaching out to her? What is she trying to tell her? Knowing that one single choice can change who is your friend, your lover, who lives and who dies, Charlotte must choose her path wisely so as not to make the same mistakes.
