Don't Go Swiftly, Darling is the second book in a series exploring what happens to the children of those fairy tale characters who lived "happily ever after." Set in 17th century Spain, Don't Go Swiftly tells the story of Catalina, Cinderella's eldest and most wilful child, who has fought her arranged marriage since the day she was first told about it. When her husband-to-be sends notice of his return, Catalina does what every princess should do in that situation: she runs. With her brother Rafael at her side, who is running away from problems of his own, she breaks away from their parents' watchful eyes and decides to explore what life is like outside the castle walls.
Don't Go Swiftly, Darling turns fairy tale conventions upside down, taking the reader on a journey through heartbreak, growing up, true love, and dealing with the past.
