One-year-old Iris is deaf. Her parents, Ben and Maggie, are devastated. So are their close friends Isobel and Eric. Isobel knows that her decision, taken years ago, not to have her own children vaccinated against measles is to blame for Iris's deafness. And Ben knows this too. To make matters worse, Isobel is the woman he fell in love with in his twenties - the woman who married his best friend. As he and Maggie start legal proceedings, Isobel's world begins to unravel. Lizzie Enfield's compelling new novel explores the hearts and minds of ordinary people as they struggle to come to terms with the choices they've made. Acutely observed and utterly gripping, it explores love and loss, guilt and recovery, with humour, honesty and page-turning prose.
