My name's Griz. My childhood wasn't like yours. I've never had friends, and in my whole life I've not met enough people to play a game of football. My parents told me how crowded the world used to be, but we were never lonely on our remote island. We had each other, and our dogs. Then the thief came. There may be no law left, but if you steal my dog you can at least expect me to come after you. Because if we aren't loyal to the things we love, what's the point? A boy's life-changing journey through the ruins of our world to bring back the family dog, this is a fiercely compelling tale of survival, courage, and hope.
