About This Book

The sharp bite of winter air mixes with the creak of wooden beams in a hidden cabin by the cold canal. Etta’s heart races as she discovers this secret place—a shelter for her and her siblings. But when Walter appears, guarding his own escape, will they find a way to share warmth and hope before the frost takes hold?

Quick Assessment

Through the Lock tells the story of eleven-year-old orphan Etta Prentice, who seeks a safe home for her and her siblings along a newly completed canal. When she discovers an abandoned cabin already inhabited by twelve-year-old Walter, the two must cooperate to survive a harsh winter while keeping their refuge secret. Suitable for middle-grade readers, this novel explores themes of family, resilience, and friendship with no mature content concerns.
