When thirteen-year-old Lena is taken from Manchester’s back-to-back terraces to the imposing Norfolk House in the dark Peak District after a family tragedy, she expects safety. What she finds instead is a house full of silences — and people who are desperate for her to keep them. The servants watch everything. The master of the house, Henry Birtles, is far more dangerous than he first appears. Even Mrs Birtles, elegant and distant, seems to be hiding something behind her careful smiles. And beyond the walls of the house, the mill and the surrounding hills hold secrets that refuse to stay buried. But there's a problem. Lena Matthews has never been good at keeping quiet. She asks questions she shouldn’t. She says the wrong thing at the wrong time. And in a world where girls are expected to stay unseen and unheard, that makes her both a problem — and a threat. As she is drawn deeper into the mysteries surrounding Norfolk House and beyond, Lena begins to uncover more than secrets about the people around her. She starts to understand the rules of a world built to keep girls like her in their place — and what it might cost to break them. Set against the backdrop of Manchester in Edwardian England, Glossop Girl is a powerful coming-of-age story of courage, injustice, and a girl determined to find her own voice in a world that would rather silence her.
