The breathtaking new novel from the author of STILL ALICE, now adapted into an Academy Award-winning film starring Julianne Moore. Joe O'Brien is a Boston cop; his physical stamina and methodical mind have seen him through decades policing the city streets, while raising a family with his wife Rosie. When he starts making uncharacteristic errors, he attributes them to stress. Finally, he agrees to see a doctor and is handed a terrifying, unexpected diagnosis: Huntington's disease. Not only is Joe's life set to change beyond recognition, but each of his four grown children has a fifty-fifty chance of inheriting the disease. Observing her potential future play out in his escalating symptoms, his pretty yoga teacher daughter Katie wrestles with how to make the most of the here and now, and how to care for her dad who is, inside, always an O'Brien. Praise for Inside the O'Briens: 'I urge you to read this book. The story is so uplifting and redeeming that it fills you with hope ... Quite simply brilliant' Judy Finnigan 'Devastating. We climb into the hearts of a normal, chaotic, loving family. A story about the resilience of love in the face of a tragic, inevitable fate' Julie Cohen, author of Dear Thing
