Norah and Gavin Stoakes live in a peaceful English village until World War II causes them to be evacuated to Toronto. Norah, an independent ten-year-old, is angry with the evacuation and resents having to care for Gavin. Five-year-old Gavin does not understand the evacuation and is confused and frightened. When they arrive in Canada, Norah and Gavin are placed with Florence Ogilvie, a bossy and cold widow and her timid spinster daughter, Mary Ogilvie. The Ogilvies only wanted Gavin but were convinced to take Norah as well. Norah is acutely aware of their preference toward Gavin, rather than her. While Gavin quickly settles into his new home where he is spoilt and coddled by Florence, Norah cannot settle. She dislikes Florence, is bored in her strict new home, is unpopular at her new school, begins to wet the bed, and constantly worries about what is happening to her family in England. As weeks go by, Norah’s resentment of Florence increases. Although she begins to make new friends, her misery increases as she realizes she cannot return to England for much longer than she was originally told. After Florence and Norah have an argument, Norah decides to run away and return to England on her own. She originally leaves without Gavin but decides she cannot leave him to be spoilt by Florence in a foreign country. She takes him with her but they only get as far as the train station before Norah realizes her plan is impossible. They return to the Ogilvies, expecting punishment but find that Florence and Mary have been very worried. Florence apologizes for ignoring Norah in the past months and asks if they can begin again. Norah accepts the offer and attempts to try to live happily in Canada. Life begins to improve and Norah accepts Canada as her temporary home for the duration of the war.
