Discover the gripping new YA thriller from the bestselling author of The One Memory of Flora Banks and This Summer's Secret.
Two girls meet on a train journey.
One of them - privileged, chaotic - is heading to an exclusive Swiss rehab centre following months of partying and living wildly.
The other - who couldn't be more different - is down to her last penny, running away.
When they get off the train they are both pretending to be the other. Just for a short period, of course. Just until the rehab stint is over . . .
