Molly and Beth are best friends and love spending time together. But when their two families move in together, maybe they are a little too close for comfort! Out shopping one day they need to avoid the most embarrassing encounter ever with Molly’s mum, and hide in a shop they had never noticed before. When they leave by the side door, they realise immediately that something is not right! Transported back to the past, where mobile phones don’t work and the world feels very different, they realise that they have a chance to see the world through their parents’ eyes. Before finding their way home, can they see what their own pasts looked like?
