A girl bursting with imagination and enthusiasm, Jane is condemned to live a quiet life in Toronto with her timid mother and tyrant of a grandmother. Her father is dead and as she contemplates the moon in the sky every night, she daydreams of moving away from her grandmother’s house. One day, Jane is shocked to learn that her father is in fact alive and well, living far away in a house called Lantern Hill on Prince Edward Island. Receiving an invitation from him to live there for the summer, she accepts with delight, and discovers a whole world there full of color and fun. She will need to draw on every resource of strength she has, when she finds out the truth about why her father and mother live apart. Her grandmother disapproved of her parents’ marriage from the beginning and contrived to split them up, against their knowledge, by lying to them both. Even worse, Jane learns that her father is planning to divorce her mother in Boston, so she bravely sets out alone on a two-day trip, risking illness and danger, to stop him. Can she get there in time, and will she be able to convince her father to love her mother again?
