When new girl Millie shows up at Lena’s boarding school, she arrives with a question. Why is Lena pretending to be someone she’s not? Lena ignores her. Until Millie shows her photo after photo of someone who looks like her. Exactly like her. Intrigued, Lena agrees to meet her look-alike, Saskia. Saskia is wild. And rich. And money is something Lena desperately needs if her mother is to stay in the care home she currently lives in. So when Saskia offers Lena cold, hard cash to stand in for her at family events, Lena finds she can’t say no. Sometimes, she doesn’t even want to say no—to the weekends away, the beautiful clothes, the amazing food and Saskia’s on-again-off-again boyfriend, Rhys. Until, of course, she agrees to one last job. The one she definitely should have said no to. Because that job might be the last thing she ever does.
