Cora Cash (get it?!), a 1890s New York society “princess”, travels to Europe with her mother in search of an aristocratic husband (most likely in need of her cash). She gets as far as Dorset, gets knocked off her horse and ends up marrying a Duke.
All a bit Mills & Boon, but fine for easy reading on trek in Nepal.
