The Cartographer's Daughter

She's spent her life helping her father map estates for wealthy landowners. She knows every grand house in three counties by its hedgerows and boundaries, but she's never been invited inside one. When her father falls ill, an earl hires her to finish the commission herself—the first woman to survey his lands. His mother is horrified. The earl finds her arguing with his groundskeeper about drainage ditches and can't stop thinking about it.
