Holly Thorpe has it all – a handsome boyfriend, a place waiting for her at Cambridge University, and wealthy parents who love her dearly – but something isn’t quite right and she doesn’t know what that is.
Sadie Wilson is everything that Holly isn’t. She’s loud and brash, bawdy and morally bankrupt. She has no future and no money, and only a life of vice and sin waiting for her.
But when Holly and Sadie inexplicably swap places, they are each of them hurled into a life they could never have expected.
The well-spoken and chaste Holly finds herself falling into Sadie’s dark and sordid world, with no inhibitions suddenly to hold her back.
And Sadie is now Holly- a dyed-in-the-wool criminal in a land of sports cars and manor houses who suddenly has great wealth within her reach.
As both girls find themselves drawn into their new roles, they must each ultimately make a choice.
Will they fight and struggle to achieve their dreams?
