Bex and her identical twin sister Naomi used to be close. They used to be able to finish each other’s sentences, used to know exactly what the other was thinking. They were a matching pair.
And then something changed.
But Bex didn’t even realise until it was too late. When Naomi walks out of the house the night before their last GCSE exam and doesn’t come back, Bex has to think hard about how to find her.
What happens next will force Bex to unpick their shared history and the memories, following Naomi’s trail through their family, their past and all the way to the blinding lights of the Hemisphere music festival. Everything she thought she knew is called into question.
With her worries dismissed by their parents and ignored by her friends (and with Naomi's friends nowhere to be found) the only person Bex can trust is a stranger – Josh – as she tries to piece together a picture of the person she thought she shared everything with. Naomi's been leading another life, one Bex doesn't recognize... and it's led her straight into the path of Max: someone else who is not what they appear.
As Bex chases Naomi, she realizes it isn’t just whether she can find her twin: it’s whether she knows her at all.
And whether she still wants to.
