Fourteen-year-old Emily is gloomily spending the summer with her mums best friend Uncle Tom, helping him renovate his house, instead of being at home hoping the gorgeous Toby will ask her out. Worse, shes broken her phone and left her iPad at her dads house. How is she supposed to survive without her tech, her BFF and her social life No one understands her despair, least of all the boomers.
Then she finds her mums old diary. MASSIVE CRINGE. But as Emily starts to read, shes stunned to discover that her mum was once a teenager too. A nineties teenager called Lila MacKay, who was VERY MISUNDERSTOOD. Its a long-forgotten era of weird fashions, TV shows and music Emilys never heard of. There are boys too, notably cute Park Boy Tom and her mums dorky neighbour Weird Nicky. And as she becomes more and more invested in Lilas teenage life, Emily begins to wonder if perhaps she and her mother are not so different after all
