Cornwall, summer of 1986. If only... thinks Tamsyn, fifteen-years-old, with her binoculars trained on the perfect family in their perfect house. If only she lived at the Cliff House, towering above the sea, with its beautiful Art Deco swimming pool. If only Tamsyn's life was as perfect as the owners', the Davenports, with their effortless glamour and privilege. If only Tamsyn's father hadn't died and left her mother working as a cleaner, tidying up after the Davenport's outrageous parties. If only Edie Davenport wanted to be her friend. If only Edie hadn't met her brother, Jago, and liked him more.
