It’s 1953, and teenage Anita Weatherby and her family have just moved to London. While her older sister settles right in, Anita finds their new school daunting. That is until a glamourous, confident new student moves to town. Stella De Vil is haughty and aloof, and surprises everyone by taking a liking to Anita.

Swept into Stella’s luxurious world of high-end fashion, Anita soon finds herself the anticipated star of the House of De Vil’s next fashion show, where she’ll be modelling a family heirloom, the Weatherby Diamond. But when disaster strikes and the diamond goes missing, Anita will have to decide on who she can trust before her life goes to the dogs.
