From the author of the international bestseller, The Unlikely Pilgrimage of Harold Fry, comes another exquisite and emotionally resonant novel about the search for the truth and unconditional love. On a foggy spring morning in 1972, twelve-year-old Byron Hemming and his mother are driving to school in the English countryside. On the way, in a life-changing two seconds, an accident occurs. Or does it? Byron is sure it happened, but his mother, sitting right next to him in the car, has no reaction to it. Over the course of the days and weeks that follow, Byron embarks on a journey to discover what really happened--or didn't--that fateful morning when everything changed. It is a journey that will take him--a loveable and cloistered twelve-year-old boy with a loveable and cloistered twelve-year-old boy's perspective on life--into the murkier, more difficult realities of the adult world, where people lie, fathers and mothers fight without words, and even unwilling boys must become men. Byron will have to reconcile the dueling realities of that summer, a testament to the perseverance of the human spirit and the power of compassion.
