England, 1940. Flora Lewis receives a tempting offer from a mysterious “flower thief.” She must go to England to find a rare variety of camellia in the garden of an old estate. Flora is forced to enter Lord Livingstone’s house as a nanny. Soon she finds in the room of Lady Anne—who died under unclear circumstances—an herbarium album with strange notes… New York, our days. Rex Sinclair offers his wife Addison to take a break in the suburbs of London. He wants to write a book, and Addison finds material for their future novel: the story of a beautiful camellia that once grew in the garden of the very queen.
