After the Great War, American heiress Ruby Vaughn made a life for herself running a rare bookstore alongside her octogenarian employer and housemate in Exeter. She's always avoided dwelling on the past, even before the war, but it seems to have a way of finding her. When Ruby is forced to deliver a box of books to a folk healer living deep in the Cornish countryside, she is brought back to the one place she swore she'd never return. A more sensible soul would have delivered the package and left without rehashing old wounds. But no one has ever accused Ruby of being sensible. Thus begins her visit to Penryth Hall.
