Hélène will accompany her on the long sea voyage and live with her sister's new family. But Catherine dies during the gruelling journey, and Hélène finds herself alone in strange new country. New France is a far harsher place than she imagined, with bitter winters and the threat of attack from the Iroquois. Will the new friendships she has made on her long voyage enable her to survive?
