Boskenna, the beautiful, imposing house standing on the Cornish cliffs, means something different to each of the Trewin women. For Joan, as a glamorous young wife in the 1960s, it was a paradise where she and her husband could entertain and escape a world where no one was quite what they seemed – a world that would ultimately cost their marriage and end in tragedy. Diana, her daughter, still dreams of her childhood there – the endless blue skies and wide lawns, book-filled rooms and parties, the sound of the sea at the end of the coastal path – even though the family she adored was shattered there. And for the youngest, broken-hearted Lottie, heading home in the August traffic, returning to Boskenna is a welcome escape from a life gone wrong in London, but will mean facing a past she’d hoped to forget. As the three women gather in Boskenna for a final time, the secrets hidden within the beautiful old house will be revealed in a summer that will leave them changed for ever.
