Dreadfully self-righteous Louisa wants to escape her grand family life in Northumberland and become a missionary in India. Imaginative and quiet Alvey has no family and spends her days in peaceful independence. The two girls could not be more different, except for their near identical appearance. So when Louisa suggests swapping identities it seems like the perfect plan: Alvey will have an elaborate country manor in which to write her book and Louisa would be free to trot across the globe. The girls tangle themselves in each others lives but at what point can you not return?
