Winter is harsh for young Emily Brontë, her sisters Charlotte and Anne, and their brother Branwell. Cooped up in the bleak parsonage, the only break from dull routine comes when they write adventures for the heroes of their secret worlds of Gondal and Angria or when freedom-loving Emily is able to escape onto the moor. Then one day, while out walking with her dog, Emily stumbles across the mysterious outcast, Heslington, whose story of lost love leaves her spellbound. There and then, Emily resolves to help him out of his wretched state whatever the danger.
